It might be realistic for kids, because kids aren't socialized as adults. In fact, we've deliberately delayed socializing them as adults more and more, and I think that's a grave error, which we've only been able to afford because we're so wealthy as a society. I think there are enormous costs, not only in the "educational" system that delays education more and more, but in the costs of that delay on the productive lifespan of people once they're finally accept as "adult", some 5-10 years after they were physiologically adult.
