The 1960s started with Jim Crow in full operation and ended in the Nixon era.

The '60s ended with Jim Crow over and done with, and Nixon thrown out of the White House - a couple of details your account left out.

Did the end of Jim Crow mean economic equality for African-Americans? No.

Did the end of Nixon mean a definitive step forward for democracy in America? No.

Was there greater "economic democracy" at that time than now? There was less income and wealth inequality, and the rise in lower incomes gave people the feeling they were part of society and not its garbage.

Was there more freedom? There were gains in freedom, and not only for middle-class white kids (and not only in America). The Civil Rights movement and radical middle-class white movement gave the impression the world was going to be changed. Was that impression confirmed by events? No. But it's not something that never existed, and neither was it insignificant.
