I think this guy is a heck of a perceptive writer and makes a number of good points all through his book. Now, some of them I disagree with, even many of them, but that's half the fun!The Great Funk: Falling Apart and Coming Together (on a Shag Rug) in the Seventies, Thomas Hine, Sarah Crichton Books (Farrar, Straus and Giroux), 2007, pages 14-15:

' . . . I have opted for a longish seventies, beginning in midsummer 1969. The Woodstock music festival and the riots at the Stonewall bar in New York City's Greenwich Village, both of which happened that summer, are often seen as quintessentially sixties events. But they really represent a transition from issue-based protest to the politics of identity and generational solidarity that characterize the seventies. And the draft lottery of December 1969 allowed draft-age young men to plan their lives, thus taking some of the urgency out of antiwar protest and setting the stage for the next phase. The end came in January 1981, when the Iran hostages were released and Reagan took the oath of office a few minutes later. Some of the economic gloom of the seventies carried over into the eighties, as the harsh inflation-killing policies of Federal Reserve chairman Paul Volcker, a Carter appointee, continued under Reagan. But from the beginning, Reagan reassured the public that we were back in more normal times, times more like the fifties. . . '
Anyway, on this particular topic, how would you bracket the 1970s?
