The Quiet Wealth Makers A new book by economists Owen Zidar and Eric Zwick sheds light on millions of Americans who've built wealth through hard work, not stock market windfalls or tech entrepreneurship.
These "everywhere millionaires" are small business owners – dentists, HVAC contractors, beer distributors – who have amassed fortunes through their own efforts.
Zidar and Zwick's research, which examines Treasury and IRS data, reveals approximately 5 million households with combined wealth exceeding $65 billion.
