The Rise of Main Street Millionaires: Hidden Wealth in Plain Sight

Why does the conversation about wealth in America always focus on billionaires and tech moguls? The popular narrative suggests that the economy is dominated by a small group of spectacularly rich individuals. However, a groundbreaking new book, "The Everywhere Millionaire," by economists Eric Zwick and Owen Zidar, challenges this assumption. Their research reveals a much larger class of wealthy Americans hiding in plain sight. These "Main Street millionaires" are not just a few outliers; they are a massive economic force that has quietly transformed the landscape of American wealth.

Key Insights into the Main Street Millionaire Class

• A Quiet Economic Revolution: The rise of private businesses has fundamentally altered the American economy. Over the past few decades, these businesses have grown to generate more income than traditional corporations, becoming the primary engine for the rising share of income flowing to the top one percent.

• The "Stealthy" Wealthy: These millionaires are often overlooked in national conversations. They are not the lightning rods of public attention, yet collectively, they wield significant political power that rivals that of the billionaire class.

• Diverse Industries of Wealth: The wealth of these millionaires is not concentrated in a single sector. It spans a wide range of industries, including legal and financial services, auto dealerships, restaurants, and even dentistry.

• The Power of Pass-Through Businesses: A crucial discovery is the dominance of "pass-through" businesses. These are privately held entities like sole proprietorships, partnerships, and S corporations where profits flow directly to the owners and are taxed on their personal returns. By 2011, these businesses generated more than half of all U.S. business income.

• The American Dream and Its Darker Side: While many of these millionaires embody the self-made entrepreneur spirit, offering better products and services, the book also highlights a darker aspect. They have often used their influence to shape public policy in their favor, lowering their tax bills and securing regulations that protect their profits at the expense of consumers.

Deep Dive: The Tax Ninjas and Their Discovery

The story of "The Everywhere Millionaire" begins with a group of young economists known as "the Tax Ninjas." Working in the basement of the U.S. Treasury Department in 2014, Danny Yagan, Owen Zidar, and Eric Zwick were tasked with a formidable challenge: to create a comprehensive dataset linking private businesses to their individual owners. Their goal was to finally answer fundamental questions about how the rich make their money and how much they pay in taxes.

Armed with a massive new dataset, the Tax Ninjas infiltrated the "dark lair" of information about the wealthy. Their most significant discovery was the pivotal role of pass-through businesses in the rise of inequality. Since the 1980s, these businesses have accounted for more than half of the increase in the top one percent's share of income. This finding challenged the familiar story of a Gilded Age-style economy dominated by capital-intensive industries like railroads and steel.

Instead, the data revealed a different picture. The wealth was not primarily generated by capital sitting idle, but by skilled professionals and entrepreneurs. The top industries for these millionaires include legal and financial services, auto dealerships, consultants, restaurants, and accountants. This suggests that the modern American economy is increasingly driven by a class of skilled service providers and small business owners who have built their fortunes through hard work and innovation.
