Communists shared alright 110 years ago in Russia, tens of millions of people failed to cope with that much prosperity and wellbeing, and then even more with unbearable freedom and peace.

I think folks may not realize that communism was more popular in the early 20th century US just because of how desperate a lot of the population became without any safety nets at all provided by the government. Educated proponents genuinely wanted to improve the plight of other folks. But, where it was practiced it became just a worse kind of power and resource monopoly - concentrated in the government instead of among a minority of robber barren types. I think the learning is you have to never stop pushing for no entity to have too much power - not the government and not private sector monopolies.
