Fascism is also on the rise because of improved technology for thought control / propaganda / public relations / advertising. Social media lets the worst of humanity band together and pool their energy.
But wealth inequality, both worse effective quality of life for the poor and increased economic power by the wealthy is I believe a main driver. Technology is just the tool. The ultra wealthy and their lackeys today have more power than ever and are more isolated and inundated with ideology that is basically insane.
I wonder if there are studies that show correlations between quality of life and fascism in different nations.
