• Bernie Sanders says Elon Musk is using his wealth and political clout to undermine US democracy.
• Musk lambasted a government funding deal and said a shutdown would be the Democrats' fault.
• "Are Republicans beholden to the American people? Or President Musk?" Sanders asked on X.

Elon Musk is wielding his immense wealth and political power to pressure US lawmakers, shifting America from democracy to oligarchy, Sen. Bernie Sanders says.

In two recent X posts, the Vermont senator called out Musk's influence over Republicans and his warnings to legislators if they don't vote the way he wants.

"The US Congress this week came to an agreement to fund our government," he wrote late Wednesday. "Elon Musk, who became $200 BILLION richer since Trump was elected, objected. Are Republicans beholden to the American people? Or President Musk? This is oligarchy at work."

"Elon Musk, the richest man in the world, is threatening to unseat elected officials if they do not follow his orders to shut down the government during the holidays," he said in a Thursday post. "Are we still a democracy or have we already moved to oligarchy and authoritarianism?"

Musk blasted the funding bill in question as bloated and overcomplicated and wrote on X that "any member of the House or Senate who votes for this outrageous spending bill deserves to be voted out in 2 years!"

He threw his weight behind Republicans' alternative bill, hailing it as cleaner and simpler. Moreover, he posted that it would be the Democratic Party's fault if an agreement isn't reached and the government shuts down.

Both Trump's team and Musk have pushed back against the idea that he's pulling Republicans' strings. Musk has said he's only bringing things to the attention of his followers, and they're free to voice their support.

The Tesla and SpaceX CEO's net worth hit a record $486 billion on Tuesday, up $257 billion from the start of the year — a figure that exceeds the fortune of the world's second-richest man, Amazon founder Jeff Bezos. Tesla stock has slid since then, but Musk was still worth $455 billion at Thursday's close.

As Sanders wrote, Musk's wealth surged after President Trump's election victory as Tesla stock rode a broader market rally, and investors wagered the automaker would benefit from Musk's close ties to the White House. Additionally, SpaceX was valued at a record $350 billion this month, boosting the worth of Musk's stake in the rocket company.

Sanders has called out Musk several times in his criticisms of wealth inequality, which often single out billionaires for having too much influence and paying too little in taxes.

"Never before in American history have so few billionaires, so few people had so much wealth and so much power," he said in a clip from "Meet the Press" that he recently shared on X.

"We can't go around the world saying, 'Oh well, you know in Russia, Putin has an oligarchy," Sanders continued. "Well, we've got an oligarchy here, too."

The progressive lawmaker has also clashed with Musk's Big Tech peers. Sanders recently told Bill Gates that he was a "very innovative guy" who deserved to be financially rewarded for his contributions to society as Microsoft's cofounder — but not to the tune of billions of dollars.

"How much do you deserve? Can you make it on a billion? Think you could feed the family? Probably. Pay the rent? Maybe," Sanders quipped.

In response to Sanders saying billionaires shouldn't exist in 2019, Meta CEO Mark Zuckerberg, now the world's third-richest person, agreed that "some of the wealth that can be accumulated is unreasonable."

• The elite group worth more than $100 billion includes Elon Musk, Jeff Bezos, and Bill Gates.
• The 16 members have grown almost $900 billion richer this year and are jointly worth $2.8 trillion.
• Walmart heirs Jim, Rob, and Alice Walton joined the club for the first time in September.

Elon Musk, Jeff Bezos, and Mark Zuckerberg are among the handful of people on the planet with a net worth above $100 billion.

Members of this elite group have amassed 12-digit fortunes by owning huge amounts of stock in some of the world's most valuable companies. Most are founders and either current or former CEOs, and some, such as Warren Buffett, would be much richer if they didn't give billions to charity.

The 16 people in this very exclusive club have a combined wealth of about $2.8 trillion, according to the Bloomberg Billionaires Index. They're worth more than Amazon or Google owner Alphabet, which command market values of around $2.4 trillion each.

All but one of them have grown richer this year, adding a net $890 billion to their collective fortunes. Walmart ($762 billion), Eli Lilly ($740 billion), and JPMorgan ($675 billion) are all worth significantly less than that.

Walmart heirs Jim, Rob, and Alice Walton joined the exclusive group in September, thanks to their net worths surging by upward of $43 billion this year.

• Many executives say they've learned valuable lessons on business from books.
• Elon Musk, Jeff Bezos, and Bill Gates are no exception.
• Here are 20 books they've said taught them a lot about business, leadership, and the forces shaping our world.

You learn by doing — but you can also learn a lot by reading.

Many influential business figures, including Tesla CEO Elon Musk, Amazon cofounder Jeff Bezos, and Microsoft cofounder Bill Gates say they've learned some of the most important lessons in their lives from books.

Bill Gates

The Microsoft cofounder usually publishes two lists each year, one in the summer and one at year's end, of his book recommendations.

"How the World Really Works"

In his 2022 summer reading list, Gates highlighted this work by Vaclav Smil that explores the fundamental forces underlying today's world, including matters like energy production and globalization.

"If you want a brief but thorough education in numeric thinking about many of the fundamental forces that shape human life, this is the book to read," Gates said of the book.

"Why We're Polarized"

Ezra Klein argues that the American political system has became polarized around identity to dangerous effect in this book, also on Gates' summer reading list in 2022, that Gates calls "a fascinating look at human psychology."

"Business Adventures: Twelve Classic Tales from the World of Wall Street"

Gates has said this is "the best business book I've ever read." It compiles 12 articles that originally appeared in The New Yorker about moments of success and failure at companies like General Electric and Xerox.

"The Coming Wave"

One of Gates' most recent book picks comes from the head of Microsoft AI.

Mustafa Suleyman's "The Coming Wave" explores the opportunities and risks posed by scientific breakthroughs like AI and gene editing.

"If you want to understand the rise of AI, this is the best book to read," Gates wrote of the book.

• Bill Gates said 2024 brought a corporate "pivot" toward climate tech, in a foreword to a new report.
• The report, by Gates's firm Breakthrough Energy, urged VCs to "prime the pump" on climate startups.
• While new climate tech emerges, proven solutions like solar energy still need help proliferating.

This has been a big year for the technologies that could save our planet.

America's first large offshore wind farm began powering homes. The Bill Gates-backed startup Graphyte opened its first carbon-removal plant in Arkansas. Another startup, Sublime Systems, secured a site and funding for its first low-carbon cement manufacturing facility.

There's also been a "corporate climate pivot," according to a report by Breakthrough Energy, a climate investment firm and startup catalyzer founded by Gates.

"We noticed a subtle, but important, perspective shift from both the investors and corporations we engage with," Gates wrote in an intro to the report, which the firm published in October with the tagline "climate tech has arrived."

More than just reducing their carbon footprint, corporate leaders "want to get in at the ground floor of new industries that, one day, will be crucial to the survival of their businesses," Gates wrote.

Other industry experts also told Business Insider that climate tech is picking up steam, and now emerging companies need more funding to scale up.

Corporate investment in climate tech

Breakthrough Energy focuses on its own partners in the report, such as American Airlines investing in a startup making hydrogen-based plane fuel. It's not the only VC firm seeing large corporations lean into climate tech more, though.

A number of long-standing corporate partners, like the chemicals giant BASF or the building-materials manufacturer Saint-Gobain, work with the nonprofit climate-tech incubator Greentown Labs to support early-stage companies.

Aisling Carlson, the senior vice president of partnerships at Greentown, told BI that the firm's oldest corporate partners have been hiring, "beefing up" their teams that invest in emerging climate tech.

"Their approach to climate innovation and their internal expertise has matured," Carlson said.

Meanwhile, other corporations are beginning to engage with climate tech for the first time. Carlson said Greentown has seen new interest from corporations that haven't invested much in climate tech, though no partnerships have been publicly announced yet.

"They are all thinking about their carbon footprint and how they can decarbonize," she added.

Don't forget about old reliables like solar

Though new technologies, like direct air capture plants that suck carbon out of the sky, can be part of the solution, Foley wants investors and politicians to remember that fighting climate change is a race against time.

"Let's deploy things that actually are cheap enough and scalable enough and ready enough," like solar power, battery storage, EV charging stations, and other tech that's already proliferating, he said.

We also have to shut down coal-fired power plants and plug abandoned gas wells that leak methane, Foley said. Efforts to stop deforestation can prevent huge amounts of carbon emissions and they're "desperately starved for money," he added.

These are the low-hanging fruits of fighting climate change.

Foley said that Gates has a history of investing in "science fiction experiments" that don't move fast enough, such as small modular nuclear reactors. After nearly 20 years of development and Gates's investment, there still isn't a single one in operation.

Sustainable aviation fuel is a similar "boondoggle," Foley said.

"That's a science experiment still, and it doesn't need or deserve billions of tax dollars," he said, adding that public funding should go to reliable solutions.

Breakthrough Energy did not respond to a request for comment.

VC can 'prime the pump' on garage innovators

Lots of futuristic climate tech just needs the funding to deploy and scale up, Gates wrote. The Breakthrough Energy report argues that venture capitalists, investors, or corporations should get in on it now, at the ground floor.

"By waiting, venture firms are only hurting their own bottom lines," the report says. By getting in early, though, investors can "prime the pump" and help early-stage companies design a product that's scalable and capable of attracting even bigger investment.

However, funding for climate tech slowed down this year, Carlson said, possibly due to investors taking a "wait and see" stance in the lead-up to the US election.

Indeed, Biden administration initiatives have boosted climate tech in recent years including the Inflation Reduction Act, the Bipartisan Infrastructure Law, and the CHIPS and Science Act.

New policies have driven more government investment in green concrete and steel, according to the Breakthrough Energy report, and the IRA created more than two dozen tax credits for investing in clean-energy projects. Breakthrough concluded those credits could unlock "more than $1 trillion in private sector investment."

However, incentives like that could change with the new Trump administration.

"What I am hopeful for is that corporate commitments to net zero targets will continue to drive innovation," Carlson said. "And if there are unfavorable federal policies, that the private sector can continue to play a driving role in ensuring at least that the early-stage climate technologies are getting to market."

• On Tuesday, Bill Gates published his annual list of his favorite books of the year.
• His top reads of 2024 include an autobiography and a book by the head of Microsoft AI.
• Here are his top books of the year — and his bonus recommendation for tennis fans.

Bill Gates has released his yearly roster of book recommendations as 2024 comes to a close.

The Microsoft cofounder published a list Tuesday of his favorite books of the year.

"All four are, in one way or another, about making sense of the world around you," he wrote in his blog post. "This wasn't an intentional theme, but I wasn't surprised to see it emerge: It's natural to try and wrap your head around things during times of rapid change, like we're living through now."

Here are his top book picks of the year:

"An Unfinished Love Story" by Doris Kearns Goodwin

This autobiography from historian Doris Kearns Goodwin centers on her life with her late husband, Richard N. Goodwin, who was an advisor and speechwriter to Presidents John F. Kennedy and Lyndon B. Johnson.

"Doris is such a talented writer that the chapters about her love story are just as engaging and enlightening as the chapters about the Kennedy assassination and the Vietnam War," Gates said of the book.

"The Anxious Generation" by Jonathan Haidt

Social psychologist Jonathan Haidt argues in his book that smartphones and social media are changing how children grow up and contributing to mental health issues in adolescents.

"It made me reflect on how much of my younger years—which were often spent running around outside without parental supervision, sometimes getting into trouble—helped shape who I am today," Gates said of the book. "Haidt explains how the shift from play-based childhoods to phone-based childhoods is transforming how kids develop and process emotions."

"Engineering in Plain Sight" by Grady Hillhouse

This book from civil engineer Grady Hillhouse offers an illustrated field guide to the modern constructed world.

"Hillhouse takes all of the mysterious structures we see every day, from cable boxes to transformers to cell phone towers, and explains what they are and how they work," Gates wrote in his blog post. "It's the kind of read that will reward your curiosity and answer questions you didn't even know you had."

"The Coming Wave" by Mustafa Suleyman

Suleyman cofounded AI firms Inflection AI and DeepMind, which was acquired by Google. He now heads Microsoft's AI division. His book focuses on future opportunities and risks posed by artificial intelligence as well as other scientific breakthroughs, including gene editing.

Gates said of the book: "If you want to understand the rise of AI, this is the best book to read."

"Federer" by Doris Henkel

Gates' bonus book pick is a visual biography of tennis player Roger Federer by sports writer Doris Henkel. It features never-before-published photos of the sports icon.

"I thought I knew pretty much everything about Roger's history with tennis, but I learned a ton, especially about his early years," Gates said.

• Bill Gates, the Microsoft cofounder, shares three kids with his ex-wife Melinda French Gates.
• They include a recent med school graduate and a fashion startup cofounder.
• Here's what we know about the children of one of the world's richest men.

Bill Gates' story is a quintessential example of the American entrepreneurial dream: A brilliant math whiz, Gates was 19 when he dropped out of Harvard and cofounded Microsoft with his friend Paul Allen in 1975.

 Nearly 50 years later, Gates' net worth of $131 billion makes him one of the richest and most famous men on Earth, per Forbes. He stepped down from Microsoft's board in 2020 and has cultivated his brand of philanthropy with the Gates Foundation — a venture he formerly ran with his now ex-wife Melinda French Gates, who resigned in May. 

Even before founding one of the world's most valuable companies, Gates' life was anything but ordinary. He grew up in a well-off and well-connected family, surrounded by his parents' rarefied personal and professional network. Their circle included a Cabinet secretary and a governor of Washington, according to "Hard Drive," the 1992 biography of Gates by James Wallace and Jim Erickson. (Brock Adams, who went on to become the transportation secretary in the Carter administration, is said to have introduced Gates' parents.)

His father, William Gates Sr., was a prominent corporate lawyer in Seattle and the president of the Washington State Bar Association.

His mother, Mary Gates, came from a line of successful bankers and sat on the boards of important financial and social institutions, including the nonprofit United Way. It was there, according to her New York Times obituary, that she met the former IBM chairman John Opel — a fateful connection thought to have led to IBM enlisting Microsoft to provide an operating system in the 1980s.

"My parents were well off — my dad did well as a lawyer, took us on great trips, we had a really nice house," Gates said in the 2019 Netflix documentary "Inside Bill's Brain."

"And I've had so much luck in terms of all these opportunities."

Despite his very public life, his three children with French Gates — Jennifer, Rory, and Phoebe — largely avoided the spotlight for most of their upbringing. 

Like their father, the three Gates children attended Seattle's elite Lakeside School, a private high school that has been recognized for excellence in STEM subjects — and that received a $40 million donation from Bill Gates in 2005 to build its financial aid fund. (Bill Gates and Paul Allen met at Lakeside and went on to build Microsoft together.)

But as they have become adults, more details have emerged about their interests, professions, and family life. 

While they have chosen different career paths, all three children are active in philanthropy — a space in which they will likely wield immense influence as they grow older. While Gates has reportedly said that he plans to leave each of his three children $10 million — a fraction of his fortune — they may inherit the family foundation, where most of his money will go.

Here's all we know about the Gates children.

Gates and his children did not respond to requests for comment for this story.

Jennifer Gates Nassar

Jennifer Gates Nassar, who goes by Jenn, is the oldest of the Gates children at 28 years old.

A decorated equestrian, Gates Nassar started riding horses when she was six. Her father has shelled out millions of dollars to support her passion, including buying a California horse farm for $18 million and acquiring several parcels of land in Wellington, Florida, to build an equestrian facility.

In 2018, Gates Nassar received her undergraduate degree in human biology from Stanford University, where a computer science building was named for her father after he donated $6 million to the project in 1996.

She then attended the Icahn School of Medicine at Mount Sinai, from which she graduated in May. She will continue at Mt. Sinai for her residency in pediatric research. During medical school, she also completed a Master's in Public Health at Columbia University — perhaps a natural interest given her parents' extensive philanthropic activity in the space.

"Can't believe we've reached this moment, a little girl's childhood aspiration come true," she wrote on Instagram. "It's been a whirlwind of learning, exams, late nights, tears, discipline, and many moments of self-doubt, but the highs certainly outweighed the lows these past 5 years."

In October 2021, she married Egyptian equestrian Nayel Nassar. In February 2023, reports surfaced that they bought a $51 million New York City penthouse with six bedrooms and a plunge pool. The next month, they welcomed their first child, Leila, and in October, Gates Nassar gave birth to their second daughter, Mia.

"I'm over the moon for you, @jenngatesnassar and @nayelnassar—and overjoyed for our whole family," Bill Gates commented on the Instagram post announcing Mia's birth.

In a 2020 interview with the equestrian lifestyle publication Sidelines, Gates Nassar discussed growing up wealthy.

"I was born into a huge situation of privilege," she said. "I think it's about using those opportunities and learning from them to find things that I'm passionate about and hopefully make the world a little bit of a better place."

She recently posted about visiting Kenya, where she learned about childhood health and development in the country.

Rory John Gates

Rory John Gates, who is in his mid-20s, is Bill Gates and Melinda French Gates' only son and the most private of their children. He maintains private social media accounts, and his sisters and parents rarely post photos of him.

His mother did, however, write an essay about him in 2017. Titled "How I Raised a Feminist Son," she describes as a "great son and a great brother" who "inherited his parents' obsessive love of puzzles."

In 2022, he graduated from the University of Chicago, where, based on a photo posted on Facebook, he appears to have been active in moot court. At the time of his graduation, Jennifer Gates Nassar wrote that he had achieved a double major and master's degree.

Little is publicly known about what the middle Gates child has been up to since he graduated, but a Puck report from last year gave some clues, saying that he is seen as a "rich target for Democratic social-climbers, influence-peddlers, and all variety of money chasers." According to OpenSecrets, his most recent public giving was to Nikki Haley last year.

The same report says he works as a congressional analyst while also completing a doctorate.

Phoebe Gates

Phoebe Gates, 22, is the youngest of the Gates children.

After graduating from high school in 2021, she followed her sister to Stanford. She graduated in June after three years with a Bachelor of Science in Human Biology. Her mom, Melinda French-Gates, delivered the university's commencement address.

In a story that Gates wrote for Nylon about her graduation day, she documented her graduation day, including a party she cohosted that featured speeches from her famous parents and a piggyback ride from her boyfriend Arthur Donald — the grandson of Sir Paul McCartney.

She has long shown an interest in fashion, interning at British Vogue and posting on social media from fashion weeks in Copenhagen, New York, and Paris. Sustainability is often a theme of her content, which highlights vintage and secondhand stores and celebrates designers who don't use real leather and fur.

That has culminated in her cofounding Phia, a sustainable fashion tech platform that launched in beta this fall. The site and its browser extension crawl secondhand marketplaces to find specific items in an effort to help shoppers find deals and prevent waste.

Gates shares her parents' passion for public health. She's attended the UN General Assembly with her mother and spent time in Rwanda with Partners in Health, a nonprofit that has received funding from the Gates Foundation.

Like her mother, Gates often publicly discusses issues of gender equality, including in essays for Vogue and Teen Vogue, at philanthropic gatherings, and on social media, where she frequently posts about reproductive rights.

She's given thousands to Democrats and Democratic causes, including to Michigan governor Gretchen Whitmer and the Democratic Party of Montana, per data from OpenSecrets. According to Puck, she receives a "giving allowance" that makes it possible for her to cut the checks.

Perhaps the most public of the Gates children — she's got over 450,000 Instagram followers and a partnership with Tiffany & Co. — she's given glimpses into their upbringing, including strict rules around technology. The siblings were not allowed to use their phones before bed, she told Bustle, and to get around the rule, she created a cardboard decoy.

"I thought I could dupe my dad, and it worked, actually, for a couple nights," she told the outlet earlier this year. "And then my mom came home and was like, 'This is literally a piece of cardboard you're plugging in. You're using your phone in your room.' Oh, my gosh, I remember getting in trouble for that."

It hasn't always been easy being Gates's daughter. In the Netflix documentary "What's Next? The Future With Bill Gates," she said she lost friends because of a conspiracy theory suggesting her father used COVID-19 vaccines to implant microchips into recipients.

"I've even had friends cut me off because of these vaccine rumors," she said.
