Their war weariness never went away.
The persons who lead and won WWII was the older generals and NCO's who was members of the Silent Generation that fought in World War I and survived the Depression. That generation gave us such things as Art Deco and Jazz. FDR, Truman and Ike was of that generation. The young privates and junior officers of World War II did not start to take over the country until 1960.
Baby Boomers did not start taking over the leadership positions until the 1990's.
While much of what the radical hippies did is not defend-able they wouldn't of gotten away with it if the Greatest Generation in charge of the universities and government and the culture of that time had wanted to stop it.
The greatest Generation was strong when they fought the war but by the 1960's they went weak and permissive.
Earl Warren was not a baby boomer.
This needed repeating. Now, if the conservative Boomers on this thread would just stop whining that we owe them, things would settle down.
Very good points you've raised there.
