I do not think it is naive to think that one (or many) can change the world -- the world is a summation of all the people in it; consensual reality is more or less a vote that we all cast. To me, it is rather easy to change the world -- in fact, it is impossible NOT to change it. It *is* changing. The sad thing IMO is that people seem to be rather short-sighted and definitely impatient -- these things take time. There are many "trickle-down" effects of cultural ideas -- the 60s *did* change the world, just not all of it, not all at once. I, for one, as a child of a the 70s definitely appreciate that the 60s existed. The cultural changes that are happening today might not be happening if not for the waves begun in the 60s.

Just my $.02 from over here at the edge of the bell curve.
