This begs the question of how one helps people who are fundamentally (a) inadequate, and (b) lacking the inner motivation to do anything about it. There are many problems in the world for which no solution is actually possible and I rather suspect this is one of them. The better approach, therefore, is to recognize that (a) many people cannot be helped, (b) they are unfit for any sort of responsibility, and (c) therefore our present system of governance whereby their votes are just as good as the votes of the tiny percentage of people who bother to become informed about real-world matters of importance and then cogitate over them, is obviously the wrong approach to ensuring adequate outcomes.

We don't expect small children to understand that putting their hands into food blenders is unwise; instead, we put the machines into cupboards high up and well out of reach. We have to accept that many people - perhaps the vast majority - need to be kept from self-harm and from harming others simply because they will never be capable of coherent thought and responsible behavior.
