I'll do a two part reply here.
With how things are set up, the more resources you have, the more insulated you get. Maslow's hierarchy of needs state that unless you situate the base needs, you really cannot get to be the best person possible (paraphrased).
America has always thought itself clean and away from all the antics we've seen in dictatorships all over the world. But when one looks closer, the issue is that if authoritarianism gets hold here, it is more ruthless potentially than anywhere else. That's why you always see Hollywood movies that shows how destructive it could look. In fact, I suspect it would be way worse here that you'd make the most stark dictator multiply orgasmic with envy.
This country was founded on not wanting to answer to anyone. The problem with that mentality is that there's always someone one has to answer to. Anytime people's access to resources get threatened, no matter what socioeconomic level one is at, there will always be a visceral reaction.
I don't remember much from my American history I took in high school (which is sadly better than what most Americans get). I also have read a lot of different things about the USA. From various perspectives.
Division is the first thing in creating a dictatorship. Politics everywhere is trying really hard to create this more and more. Typically right wing. We've had an upsurge here in Europe recently but not as bad as people were expecting.
I can totally appreciate how right wing politics can sound very appealing to those who feel the system is no longer working for them. I can also appreciate how those who feel disempowered don't bother to vote.
In the USA it's been so bad for so long that it's a really broken system. Without even taking about the electro college... The crap politicians do in power is ridiculous and the emphasis in business first has created this weird society that to anyone else (especially with the current government) seems like some dystopian world.
The USA has felt for so long like it was some special country, bigger, better, more free than anyone else that is gone to it's head. There's really nothing special about the USA compared to other western societies.
By the time anyone realises that the USA is no longer democratic it will be too late. It's borderline now. One more term of this government and I'm pretty positive the Constitution will be adjusted with supreme court backing of course.
Unfortunately a lot of the language used in the USA is religious and most think there is only one thing to answer to... Even though the USA is the only purely secular country around. Something a lot in the USA don't like to hear.
I lastly, I'm aware of Maslow's hiearchy of needs. I'm also aware of the situation in the USA where this doesn't get met very well and why things with the protests happen to this extent. Especially with the current situation of lockdown and joblessness.
Like I said I understand the anger and everything but what did looting setting building on fire and damaging property achieve?
