Exactly - bad implementations of communism, bad implementations of capitalism, bad implementations of whatever utopian form of government we can dream up in theory, all suffer b/c they are bad implementations, even if in theory they are perfect. Beyond that, some theories may themselves just be "bad" overall, if the theory is too far removed from reality.
One problem that the USA has found for itself is having allowed itself to devolve to become a 2-party system, where no other parties matter. This is a fundamental phase shift b/c at that point the parties no longer try to accomplish positive aims, and instead merely try to "not" be the other side. Biden won b/c he wasn't Trump, Trump won b/c he wasn't Hilary Clinton, Obama won b/c he wasn't Romney, or McCain, Bush won b/c... well it goes back many, many decades. Afaik, no democracy has ever survived that.
Nor does it seem to matter even, b/c regardless of who wins, the wealthy are in charge. School shootings are a perfect example of that - our CHILDREN are being MURDERED... and nobody gives a damn. I recall one poll result where 80% of the American people were for some form of gun control, and that rose to >90% of responsible, registered gun owners! Also that was a decade ago, so surely after all that we've seen since, it could be even higher? There is nothing that engenders bipartisan efforts in Congress these days - but 80-90% agreement among the American populace is astounding!!?!! However, it does not matter one bit what we want - b/c the lobbies want something else there, and they are willing to pay 10-fold more than the counter-lobby, hence children continue to be murdered all across the nation (typically in poorer schools though).
In addition to being horrific, that example also reveals that our democracy is beyond broken, it is no longer "democracy" at all, but a plutocracy where regardless of whoever votes for whatever goal to be done, the rich control what actually gets done, regardless.
So to fix something like that... assuming that it even could be fixed, would take... I have no idea. But going to a political rally will not begin to cover it. We may literally have a civil war coming up, or at least it is highly expected (among experts, it is said) to have some kind of "constitutional crisis event", much like the January 6 protests where Donald Trump attempted the most ineffective coup that I have ever heard of, yet still was solidly an attempt.
And one potential reason for all that is that whereas the wealthy previous wanted to use middle-class workers to be the underpinnings of society - doctors, researchers, lawyers, engineers, etc. - now they gloves are coming off, and they would have divide the world into the haves vs. have-nots. That CPG Grey Rules for Rulers really helped me see this clearly, though also depresses me:-).
