New research drawn from Treasury and IRS records reveals that America's real wealth engine is not tech startups or hedge funds but millions of private business owners scattered across every state, a finding that challenges decades of progressive assumptions about who gets rich and how.
Economists Owen Zidar and Eric Zwick dug into federal tax data, matched returns to individual businesses and their owners, and found roughly five million U.S. households sitting on at least $5 million in wealth. Their combined fortune exceeds thirteen times the wealth of the entire Forbes 400. The findings appear in a new book, The Everywhere Millionaire, published by Henry Holt and Co.
The numbers rewrite the popular story about American wealth. About three million of those households belong to private business owners with an average net worth of roughly $25 million. Three-quarters of them started their own companies. The vast majority did not inherit money. They are not the coastal elite of progressive imagination, they are beer distributors, HVAC contractors, and restaurant owners who built something from nothing and kept building.
Zwick, an economics professor at the University of Chicago Booth School of Business, told CBS News that the research upends the Silicon Valley fixation that dominates media coverage of wealth.
"This is not just a story about wealth being on the coast, Silicon Valley and finance. This is a much broader phenomenon, and also much closer to home for a lot of Americans."
The Forbes 400 captures headlines, but Zwick put that list in proportion. Elon Musk and his peers on the list account for just three to five percent of total household wealth in the United States. The "everywhere millionaires", Zwick's term, dwarf that figure, and their wealth sits in businesses most Americans walk past every day without a second thought.
"You're walking down the street, you look at a truck that's delivering beer, and if you look on the door, you see the name of the beer distributor, and then you go look them up, and you're like, 'Oh, that's an everywhere millionaire.' And you start to see them everywhere like that."
The profile of a typical everywhere millionaire is not what progressive wealth critics tend to describe. The median age is 62. Most are married. They are somewhat more likely than the general population to hold a college degree, but not by much. Many never stopped working.
"Often they're still quite obsessed with what they're doing."
One case study in the book is Dick Portillo, who grew up poor in a Chicago housing project. In 1963 he scraped together $1,100 and opened a hot dog stand. He grew that single stand into a large regional restaurant chain and eventually sold the business to Berkshire Partners for $1 billion.
Portillo's story is dramatic, but Zwick said the motivation behind it is common among the entrepreneurs in the data. Most did not set out to get spectacularly rich. They wanted to work for themselves.
"Freedom, independence, is almost more important to a lot of them when they're starting, Portillo similarly, than 'Oh, this is going to make me hugely rich.'"
That instinct, solve a real problem, own the solution, keep at it for decades, produced more aggregate wealth than the entire Forbes list. And it happened in industries that rarely make magazine covers: plumbing, food distribution, auto repair, heating and cooling.
The research also highlights a structural feature of the tax code that helped these owners accumulate wealth. Many of the businesses are organized as pass-through entities, LLCs, sole proprietorships, and similar structures, whose profits flow directly to the owner's personal tax return. That structure avoids the double taxation that hits traditional corporations, and a separate provision lets pass-through businesses deduct twenty percent of their income.
Zwick was direct about the effect:
"You pay lower tax if you're getting your income through one of these businesses, even if your labor is going into running the business. It has made them richer than they otherwise would have been, and it's an important part of the story of their growth over the last 40 years."
That tax advantage is frequently targeted by progressive lawmakers who frame pass-through deductions as giveaways to the wealthy. Zwick's data suggests the beneficiaries are not hedge-fund managers gaming the system but owner-operators who built companies in their own communities, exactly the kind of enterprise that politicians on both sides claim to support.
For years, a dominant strain of progressive economic argument has held that the American economy is rigged in favor of a tiny elite, that upward mobility is a myth, and that wealth concentrates through inheritance and financial manipulation rather than productive work. Zidar and Zwick's data tells a different story.
The vast majority of these millionaires did not inherit their wealth. They built businesses that solve what Zwick called "tactile, tangible" problems, the kind people encounter every day. He pushed back directly on the pessimism that shapes so much economic commentary.
"The prevailing narrative is very pessimistic relative to our reading of the data, but it's not necessarily where people are looking."
Zwick also argued that the path these entrepreneurs followed is not closing. Technology will reshape industries, but the underlying demand for real-world services is not going away.
"The problems that these people are solving are tactile, they're tangible, they're problems that people experience every day. Technology will change what these businesses look like, but these tactile, real-world problems are still going to be there. HVAC is still going to be a need."
And he sees room for a new generation to follow the same route: "There's a lot of room for people to take new technology but solve these old problems."
The book's findings echo a 1990s bestseller, The Millionaire Next Door, by Thomas Stanley and William Danko. That earlier work argued that many American millionaires were not living on Park Avenue but on Main Street, ordinary people who built wealth through disciplined saving and investing. Zidar and Zwick's contribution adds federal tax data at a scale Stanley and Danko never had, confirming the same basic picture with harder numbers and a sharper focus on business ownership as the primary engine.
Zwick said the research leads him to a conclusion about the broader promise of the country. The American Dream, he told CBS News, "is more alive than most people think."
That line will irritate anyone whose political project depends on convincing Americans that the system is broken beyond repair. Five million households and thirteen times the Forbes 400's wealth say otherwise, and most of it was built one truck, one storefront, one customer at a time.
