Brazil Election
I suspect that part of it has to do with dwindling economic conditions for the vast majority of the population.
Instead of looking for the actual culprits, say, the billionaire class, a significant portion of the political class, and massive multi-national corporations, these politicians do what they've always done, they demonize minorities, vulnerable people and so on.
It's easy to do because you rarely see billionaires in real life, nor are you invited to board meetings in Goldman Sachs or are invited to Davos. But gay people, indigenous people, poor people - those you see every day. "They are responsible for your problems, not us."
And then there are other factors too, nationalism, religion, tribalism, etc., and you have a recipe for a disaster.
That's what I make of it anyway.
