Rights Without Responsibilities
Old people used to be more respected when they were seen as more useful for the larger community and frankly, there were less of them. Today in atomized, resource hungry, quickly changing society they are less help than they have ever been and the means needed to keep them involved in the community need to be rather extensive.
I agree that learning by practice is very good, do you mean that as learning by experience? It is rather troublesome though to organize practice for children if the parents work and the school system is suboptimally built. I think organizing partial employment for children from the age of 12 could be useful in that regard.
As for rights and responsibilities, they aren't from the same narrow category at all, I don't see a good use for a word for the sum of those sets. Both rights and responsibilities are granted by the ones that wield power, but they don't need to inherently balance each other out. It's true that most productive societies do have some partial balance between the rights and responsibilities, so it seems to be useful for the benefit of the societies. And if the US falls behind because of unbalance of rights and responsibilities, other societies with better structures will come ahead and your society will have an opportunity to correct itself and the humanity will learn a lesson.
You say that young people (that you know) goaded by fools grew demanding and stupid? Well it's real pity that the previous generations haven't fulfilled their responsibility to bring the new generation up to par. I don't know young Americans, but why in your opinion the older generations failed them?
