Once upon a time, white male Protestants ruled the roost in the United States. You got into a fancy school if your father had gone to the fancy school. You got a job at a white-shoe law firm or climbed the corporate ladder if you golfed at the right club.
Then we smashed all that. We replaced a system based on birth with a fairer system based on talent. We opened up the universities and the workplace to Jews, women and minorities. University attendance surged, creating the most educated generation in history. We created a new boomer ethos, which was egalitarian (bluejeans everywhere!), socially conscious (recycling!) and deeply committed to ending bigotry.
