Yes. This strikes me as obvious. People don't have the sort of impulse control you're implying by default, it has to be learnt just like anything else. This sort of environment would make you an idiot if it's all you've ever known.

You might as well be saying that you can just explain to children why they should eat their vegetables and rely on them to be rational actors.
