It does go to show that the sentiment which gave birth to the Trump phenomenon is not unique to the USA. As if there was ever any doubt. Italy had Berlusconi (and before that, Mussolini), France has the LePen family, Austria has a popular right-wing nationalist party, and so on. Smug Europeans have nothing to be smug about.
It’s a problems that has its roots in hierarchical class society. It doesn’t benefit the majority who live in it. The only way electoral democracy (or any open society) can be maintained under such a system is to have a powerful system of propaganda to keep the masses convinced to act counter to their best interests. And it has been shown, repeatedly, that the level of propaganda needed to do that, and the level of propaganda needed to sell fascism are dangerously close to each other
Reality-based politics is the only practical antidote to fascist myths, and that same reality is fatally toxic to class society, so absent revolutionary change it won’t happen and fascism will be an ever-present risk.
