I only meant to say that the social movements that youth were involved in during the 60's and 70's were far more widespread (and much more radical) than those of today.
Because of that, I really don't hold much hope in today's youth having much more of a transformative aspect on society than the youth of the 60's and 70's did, and even that was quite limited.
My greatest hope for social change is in the legalization of marijuana and the so-called "psychedelic renaissance". As more people are exposed to these substances, their world view and conception of what is possible could radically change. These substances were powerful catalysts of social change in the 60's and 70's (and were one of the main reasons for their violent repression), and could become so again.
