Labor, filed under capital

Take an engineer paid partly in restricted stock. The grant vests and the IRS calls it wages. The shares climb for three years and the same money comes back as a capital gain — lower rate, different name. One person, one job, one stream of pay, sorted into two categories by nothing more than when the price moved.

That quirk, Zwick and Zidar argue, is hiding one of the larger political facts of the last forty years. The decline of labor's share — the stat under every argument that capital is beating workers — shrinks by roughly a third once you count the stock those workers are paid in. Labor didn't lose as much ground as the series says. The series was filing part of labor's income under capital.

The paper doing the arithmetic, *Human Capitalists*, is blunt about the size of it. Equity-based pay ran 36% of compensation for these workers from 2010 to 2019. Leave it out, as the standard measure does, and high-skilled labor's share of manufacturing value added falls from 17% in the 1980s to 11% in the 2010s — the hollowing-out everyone narrates. Put the stock back in and the decline nearly disappears.

So the worker-owner line — the one the whole fight is drawn along — no longer runs between people. It runs through them. Same paycheck, two tax identities, split by the calendar.

The engineer on a four-year vesting ladder is labor on payday and capital when the shares mature — and the tax code is the last institution still treating those as two different taxpayers.

The objection is obvious: this is a rescue for the top. The warehouse worker and the barista get no equity grants, and recasting a senior engineer's stock as "labor" does nothing for the person who holds neither leverage nor shares. That's true. The human-capitalist story is a story about the high-skilled, and it says nothing generous about the bottom half of the distribution.

But that is exactly why the reflexive fix — tax capital gains as ordinary income, close the gap, call it fairness — points at the wrong target. For the human capitalist the gain already is labor income, deferred and repriced; taxing it as a windfall taxes the same work a second time. For the founder or the early employee it is the only pay for years of below-market cash. Raise the rate to catch the rentier and you also dock the engineer who bet a salary on a vesting schedule. The mistake the statistics made — reading labor as capital — is the one the tax fix would repeat, from the other direction.

The honest correction isn't a higher rate or a lower one. It's conceding that the category broke. We built a century of tax law and class politics on being able to tell the people who work from the people who own — then started paying the workers in ownership, and kept two ledgers anyway.
