If it was just a temporary problem politicians all over the world wouldn't be avoiding it like the plague, some hard decisions need to be made but whoever makes it is committing political suicide. I doubt the dynamics of that will change if anything it will get worse you will have a large voting population affected by these decisions who will make life hell for any politicians that hurts their bottom line.
The angry extremists on the right are overwhelmingly in office, it's not really an option to think it would go away many thought it would when Trump lost it's gotten worse.Probably not in a dramatic way. The angry extremists on each side will have to cool down. The rest of us don't need to change very much.
