I mean the richest nation on earth bar none. The amount of wealth in the nation. Literally that. The USA cannot plead poverty as an excuse for why anything is worse there than any other nation. Do you see it now?
I don't think US-citizens by and large want that change bad enough to accept restrictions upon their freedoms and an end to low taxes, European-level wealth redistribution does not seem to be popular in the US. I suppose they'd like the result without doing it. Unfortunately that's like wanting to be great at tennis without wanting to put in the training: understandable, but not happening.
I have no doubt that American can-do and talent will get it done.
None.
Just decide what it is, what the scoreboard looks like and get it done as Americans the American way.
