The economics and measurement of who gets what and who has what (distribiution) is difficult and easily distorted. In election years, it is trampled on.
But Martin Feldstein's NBER WP 13953 ("Did Wages Reflect Growth in Productivity"?) is helpful. Productivity has been growing, as has labor's share.
