Business Owners Now Keep Half the Value Their Companies Create, Up From Roughly a Third

On the September 18, 2026 episode of Bloomberg’s Odd Lots podcast, There’s a Mind-Boggling Number of Rich People in America, the co-authors of the new book The Everywhere Millionaire offered what may be the cleanest one-sentence summary of American income inequality in circulation. As one co-author, University of Chicago Booth economist Eric Zwick, put it on Odd Lots: “The share that the owners are capturing of the pie has gone from like a third or 40% to like 50%.” The pie in question is the value produced by America’s pass-through business sector, and the shift he described is the split between the people who own those businesses and the people who work in them, according to Odd Lots (Bloomberg).

What the Owners’ Share Actually Measures

This figure measures the owners’ share of value added, which in plain language is what a business generates after paying for the inputs it buys from other businesses: the money left over to compensate the people inside the firm, whether they are workers drawing a paycheck or owners taking profit.

The universe here is the pass-through business sector: partnerships, S corporations, and sole proprietorships whose profits flow through to owners’ individual tax returns rather than being taxed at the corporate level. That is the world of law firms, medical practices, dental groups, contractors, consultancies, and the mid-sized private companies that dominate American business by count. The authors’ decomposition covers the period from 2001 to 2021, so the “50%” anchor in the headline is a finding as of 2021 data, not a live 2026 reading.

Decomposition: Bigger Pie, Bigger Slice

The reason this framing carries so much explanatory weight is that both things moved in the same direction over those two decades. The pie grew, and the owners’ slice of it grew.

By the authors’ accounting, value added per worker in the pass-through sector grew by $18k from 2001 to 2021, and owners captured $15k of that gain versus workers getting the rest. Zwick’s framing on the podcast was that this quantitatively explains rising U.S. income inequality as roughly 50% pie growth and 50% owners capturing a larger share. Those per-worker figures describe how a gain in value added per worker was split between the two sides of the ownership line. They are not owner incomes, not worker wages, and not raises anyone received.

Why This Lands on Your Paycheck

The authors’ explanation for the shift leans heavily on skilled services, where the demand at the top is driven by a scarce factor. The demand for skilled services at the top that doctors practice is really driven by the scarce factor being brought, which is the expertise and reputation of the folks at the top of the business, so they can raise the price. Zwick added that the American Medical Association helps restrict the supply of doctors, noting the U.S. has 30% fewer doctors than the OECD average. As demand grows, a lot of surplus is generated, but the practice does not need to pay the nurses or assistants any more to capture it.

For an individual reader, the practical implication is not abstract. In a pass-through business where expertise and reputation are the scarce ingredient, the surplus accrues to the equity holders at the top of the org chart. Whether the last two decades of American growth showed up in your bank account depended less on what industry you chose than on which side of the ownership line you were standing on inside it. Employee stock, partnership tracks, and equity in the closely held businesses where you spend your day are the mechanism by which the shift Zwick described actually reaches a household.

Bottom Line

The Everywhere Millionaire’s central finding is a single number that has moved from a range the authors described as a third or 40% up to 50%, measured through 2021, according to Odd Lots (Bloomberg). Half the story is a bigger pie and half is a bigger slice for owners. Both halves point to the same conclusion for anyone building a career or a balance sheet: ownership is where the compounding happens, and wages alone will not close the gap the data describes.
