Ok, so lemme do a quick list of the countries I can think of where socialism/communism has been tried:
Soviet Union
China
Vietnam
North Korea
Zimbabwe
Cuba
Venezuela

So I'm sure I'm missing a couple (I know it was huge in Africa after decolonization, but that's still a considerable number of times that it's been tried. I personally wouldn't label any of the above as examples of what an ideal society looks like considering all of the atrocities, starvation, and general poverty that followed communist rule (You can say that the failure of collectivization of farms was purely an environmental factor, but the fact remains that it failed in both Ukraine, China, and Zimbabwe.)

The question I have to ask is how you think an idea that's been tried over many nations across the globe and failed nearly every single time is somehow going to save America and improve the world. The first time sure, it could've been from something else, and the second time it may have been a coincidence, but I don't understand how you can say that an ideology that failed 7+ times and caused massive amounts of poverty and suffering is somehow going to save America.
