To the contrary, a set of voters in the US were shown to not vote in their own self interest, those Trump voters who were acting on an ideology despite the unlikely chance of a beneficial outcome. It's a rather troubling shift, part of the Internet age in which they get into a space where they only hear a certain set of voices (such as FOX News) and don't look farther for the rest of the story. They voted against health care, they voted against support for their communities. They voted to try to impose their religious beliefs on their neighbors, despite the separation of church and state. They let him feed into their basest biases, their bigottry, because they saw him rant, mimic, lie, discriminate, and generally misbehave in a way they have kept hidden because it isn't socially acceptable. This barely-literate demagogue not only convinced them to vote against their own best interest, he unleashed their misbehavior.

Trump isn't thinking about youth and the future, EXCEPT in the context of the younger members of his family and their ability to continue to enrich themselves at the public trough. And as he does this out in the open, those voters (described above) cheer him on. He will trip up, and he will fall. But it will be a big messy splat when it happens, and this system of government will return to functionality, but a lot of rules will need to be firmed up and cleared up.
