There are obviously multiple factors that go into this, but I think the big ones are the systematic destruction of the US educational system and the wealth inequality caused by late-stage capitalism. Fixing the education problem will take decades. Fixing the wealth inequality could be done quickly, but things will have to get worse before people begin to agree that it needs to happen. I’m confident that things will eventually get better. I am no longer confident that it will happen soon or without violence.
Similar things are happening in Europe, with the rise of the extreme right, but the situation there is not as far along as it is in the US. I think Europe still has a reasonable chance of avoiding the worst of this.
I don’t actually disagree with you. My point was that there is nothing that could be done to fix education quickly while it would be possible to fix wealth inequality overnight. That doesn’t mean I think there’s a chance of it happening any time soon.
