The bigger question is "What can be done about it?"
I think all of your observations are correct. I think you missed a huge one but I'll get to that last.
The only actionable answer I can come up with is to learn more about the Founders, to acculturate to them to become more like them.
As you know, I have the whole audio book thing and it is quite successful. Not as much as I would like - but better than I initially hoped.
However, I've come to notice that the amount of hatred I see when I remind people that the Founding Fathers were themselves protesters and were themselves activists is palpable. Conservatives do not want to remember that part.
"What can be done about it?" We need to be activists and protesters like the Founding Fathers were. Involved, every single day, doing something actionable.
I have not seen any other actionable answer to the question. But it is clear that we cannot vote our way out of this problem. The only way out is to activist our way out, just like the Founding Fathers. They are the "model".
I always wonder if we are simply dealing with social forces which cannot be overcome because they are like a force of nature inherent in human societies.
We should try to steer the future, though we may be inevitably overcome by a larger effect we cannot easily see.
