What is lacking today is that people are not in any way experimenting with a different way to live, a different way to feel, a different way to be.
The things that troubled young people in the '60s and the things that trouble young people today seem quite different, in the sense that the troubles today are mostly material trouble - I can't get a job; I can't support a family; whereas the complaints in the 1960s were more spiritual - I don't feel like a real person, or something like that. However, they are related.
Whether you're complaining about spiritual emptiness or material emptiness, you're ultimately complaining about the same system that's creating both kinds of emptiness. That's the link between The Greening of America of 40 years ago and the way young people are feeling today.
