We're a product of a very, very strange time and place in history where the average person had at least some recourse against tyrants. From prehistory to about the mid-point of the 20th century, if you were alive on planet Earth, there's a near guarantee that you lived life basically as a possession of some person or family who controlled where you lived, where you could go, what clothes you wore, what work you could do, whether or not you would be educated, who you would marry, if you would have children, which god (if any) you could worship, what you could say, and even whether you lived or died.

That was your existence.

This whole thing where you have some control over your destiny? That's the fragile set of changes. Someone behaving like Trump is historically insanely durable.
