That's all but impossible here.
I talk regularly about how the biggest culprit in this mess is a political/electoral system that incentivizes and rewards the worst impulses of its participants. But I can't say that even fixing it would be enough, though we do have to try.
This cancer is now cultural. And it seems that the only way you can fix a profound cultural problem is culturally. That means the biggest, most influential voices on the ends have to lead the way. They have to reverse course, away from division, clearly and completely.
Then, each end of the spectrum has to do what it hasn't done for a long time: Hold its own tribe accountable.
I don't see how we're close to any of that happening, and I don't know what stops this whole thing from getting even worse.
I agree with you here. (I've thought a lot about what sort of political arrangements would best preserve/extend democracy, but allow for minority interests to be protected, while also providing essential political stability, with, if possible, some way to allow special input/advice from people recognized as particularly wise. What the Founders wanted, I think. But this sort of change would be very hard to bring about even in a stable situation -- where we are now, it's just a distraction.
The key is to understand
why we have sunk into this. The book by Katie Roche I've just mentioned has an interesting analysis of the 'woke' generation -- it makes sense to me, but she doesn't cite any supporting hard data.
I believe that both America's supreme position in the world, militarily and economically, for the last half of the 20th Century, and then its slide down starting in this century, must have a lot to do with it.
Leftists point to growing extreme inequality, the growing economic precariousness of people in the non-college-educated sector [and not just them] ... and they're not wrong. This has upended the Republican Party and is, I think, behind the Trump phenomenon.
I don't see any change in a positive direction coming. And, there are other converging negative developments that are not internal to America but will affect it.
Which is why I think we ought to be talking about a peaceful separation.
If you haven't heard of him, you might like to look at the work of Francis Buckley. He would like to see the Republicans become 'The Republican Workers Party', with essentially the same program as European Christian Democrats.
