To what extent were the sixties a turning point in American History?

The sixties were the age of youth, as 70 million children from the post-war baby boom became teenagers and young adults. The movement away from the conservative fifties continued and eventually resulted in revolutionary ways of thinking and real change in the cultural fabric of American life. No longer content to be images of the generation ahead of them, young people wanted change. The changes affected education, values, lifestyles, laws, and entertainment.

To the same extent that pretty much any other decade was a turning point in American history. In any ten-year period a whole lot of things are going to happen that will make a large country like the USA different in many ways from what it was like before.
