Since I teach high school history, I thought I’d share a couple graphs I found for one of my classes.  During the 1920′s, GNP per capita was increasing…

But gains were concentrated the top…

Calvin Coolidge and Herbert Hoover were the proponents of supply-side economics and “rugged individualism” from 1921-1932.   Republicans spout the same ideas today.  Look at 2007 in the graph above.  Do we have any reason to think the superrich aren’t at it again?
