The most remarkable things about the decades from 1960-1980, seen from today, are the cartoonish revisionism of the aims and ideas of the times, and the fraudulent "history" that has replaced what really happened.
In terms of ideas, the times were fertile and creative, and changed the world--the world outside the beltway and the boardroom--in a big way.
That defines "important" to me. 1968 was hugely important- and reactive.
However, the winners got to do the editing, and "stuff" won.

Anyone here ever read the port huron statement?

Capitalism searches out the darkest corners of human potential, and mainlines them.
