It is hard to get past talking points and deal in economic data. Profit margins, labor costs, tax brackets can vary by industry and state. Marxists take as an article of faith that private property is criminal. Labor unions historically assumed corporate revenues are infinite. In a market economy price competition is keen to retain market share. What has not been noticed by the general popular discussion is the profound effect the Quality Revolution has had on the world economy in the the last 50 years. See W Edwards Deming, Philip Crosby, and Peter Drucker.
