The people I am in contact with, e.g. Food Not Bombs, do not appear to be particularly affluent. I don't know about their families, but I believe they're primarily working-class or lower-middle-class. (Of course if they have any energy and intelligence the System is going to make them an Offer.) The people I know to be upper-middle-class seem much fonder and more trusting of established institutions. If the current anarchist thing goes the way of the hippies, you will see more, not fewer, upper-middle-class types coming in as it becomes institutionalized. Eventually, you'll see advertising promoting "anarchy"[1] and hear people talking about getting grants. The Black Bloc is going to have its work cut out for it. -- [1] Actually, Hard Rock Cafe (?) is doing this now.
