I don’t think the original writer assumes productivity and wages should 1:1.

I think the original author wants a system like that. CEOs do not return productivity commensurate with their income, especially relative to various employees far downstream.

I will need to re-read your analysis, but could you speak to the uberization of labor, the new gig economy, the stagnant wage growth over the last 10 years, yet the S&P index’s incredible run which suggests corporate profits [along with a rebound from a scary collapse involving so many wage-earners losing their jobs and houses due to corporate malfeasance] have been doing just fine?
