I see no reason the U.S. will do anything other than flip flop between parties over time as we have done in the past. If you know anything about our political history, any yuge changes will only come glacially as long as we have the current two party system. Unless Citizen's United is gone and the average citizen becomes more engaged and actually uses the power of their vote things won't really change very much. It's likely we won't elect someone as horrible as DJT again, but never underestimate the stupidity of large groups of people being gaslit I guess.
The bottom line is that the people don't have the will anymore, even though they have the power, so the people actually in control will continue to screw the poors and throw them just enough scraps to make them happy, as they gradually shift more and more of the wealth to themselves.
