Speaking as someone who is old enough to know people who were hippies... well not at the actual beginning, more at the tail end really, and some of them still are at heart I would say it is more a reaction against governments than for them. Once upon a time government etc. used to say 'i think we will go to war now' and the public would say, 'yay, lets do that, its our patriotic duty'. Now there is a lot more questioning, for example the thing about MPs expenses, that would have been accepted in the past as only right alomg with their right to tell the rest of us what to do and how to think, and the expectation that we will defer to their greater wisdom. Now of course the earliest hippies may be thinking about retiring in the nearish future. so watch out for a new wave of hippidom now they have a bit of time on their hands!
