> Some of the XXI century most tough decision are taken by teenagers as they decide what to study or not and shape their professional future. I hardly see how the self sacrifice and high level of discipline required to study are easier than a low skilled job. Children spending so much time studying instead of earning money is an investment in their future and our future far away from enjoy themselves.

At least in the US I would say a minority of teenagers take that approach to their academic/career decisions.
