As David Frum wrote in his 2000 book How We Got Here

For half a century, Americans have been asked to choose between two myths about their country's recent past. In one, the heroes are the parents; in the other, the children. In the parents' myth, the middle years of this century were a time of peace and prosperity, the well-deserved reward for enduring the Depression, defeating the Nazis, and resisting communism. In the children's, those same years were a dark epoch of of racism, sexism, and homophobia, when Hollywood liberals flinched every time the doorbell rang, fearing it was the FBI come to tell them they couldn't write screenplays any more. In the children's myth, Americans huddled frozen and miserable (like Pepperland under the dominion of the Blue Meanies in the Beatles' Yellow Submarine) until the brave, joyous protesters of the 1960s liberated them. In the parents', a golden age of patriotism and duty was wrecked by draft-dodging, pot-smoking, hippie-turned-yuppie lowlifes. It is like the extinction of the dinosaurs: One minute giants are walking the earth, then suddenly--CRASH!--a comet smacks the planet and the giants are replaced overnight by tiny rat-like creatures.

This sums up a classic generational-gap, in which the parents see all that was good about their youth being undermined by all the thier children see as being good about their youth.
