I often see this theory, but I don't really see much evidence. The 1960s started with Jim Crow in full operation and ended in the Nixon era. There was a great deal of freedom for middle class white kids, at least personal freedom, but did the era of Cointelpro and of the Vietnam War had more democracy of any kind than the current era? Was there more "economic democracy" then? How?

The "left" or what remains of it, seems to me to be crippled by a weird nostalgia for what never was.
