Authoritarian governments don't collapse because of the "will of the people", that's a myth perpetuated by those in power to legitimize their positions. The major driver is the material conditions a society exists in.

The comparisons of Trump to Hitler as also mind-numbingly facile. Other than a penchant for authoritarianism, they share little in common. But what they do share in common is they are both emergent phenomena of their contemporary environments.
