I have to laugh when folks talk about Woodstock as some 'defining moment' in the culture of America. Maybe in the minds of the media, because it was their ilk who were represented in that throng. The upper middle class youts had the time and money from their increasingly disinterested parents to engage in activities of this sort. The population of Woodstock was very homogeneous; i.e. WHITE, upper middle class, but history wants us all to think they represented all of their age group. Alhough the media coverage helped mold the ideas of some middle and lower middle class kids to want to be like those they saw at Woodstock, most of us just went on our merry ways, not buying into the hippie lifestyle and radical politics.
We see a similar situation today in the mainstream women's movement and anti-war movement; they are largely upper middle class and overwhelmingly white, so they don't represent the nation as a whole, by a long shot. Yet it is the leaders of these groups who are contacted by the media for a take on the situation of people as a whole. VEY annoying!
I suspect there was a disproportionate number who later went into 'journalism'.
