The phrase "generation gap" has been used since'60s to describe the differences in views of young people and their parents. Personally, i don't think it's useful idea. Some young people have tradition opinions, and some older people don't. We need to look individuals, not generations.
I agree that it's important to consider people as individuals. On the other hand, i know from my own experience that the generation gap is real. My kids definitely see the world in a different way from me. They expect to get everything they want, and they expect to work less for it.
