People talk about the 'shrinking middle class' without assessing what contributed to the growth of that middle class. My suspicion is that the middle class is an artificial phenomenon propped up by government programs originally, and then sustained by unions which no longer have their clout. Thanks for providing the names of those government programs: GI education bill, federal mortgage programs, and interstate highways.
How it is that mortgages which were so wonderful for one generation turned out so bad for another? I know the answer, but just think it is interesting to point out generational differences.
