I get your point, but (also with a harsh perspective) the point isn't really to create engineers and doctors from the downtrodden.
The point is that even if you get those kids even 10% of the way of others, that might be what buys you one less person between bars. Or suffering from substance abuse. Or fueling Ponzi schemes, MLM or cults as a victim. Or living in the streets. Or voting irrationally for the next populist policy maker (in any part of the political spectrum, not being political here).
The moment you renounce to killing all of those who misbehave, you have to accept that these people are going to be your neighbors for the foreseeable future, and so it really pays to take care of the problem as early as possible, because frankly, you'll be spending resources either way.
