I am from Eastern Europe and I share this sentiment when I see anyone from the West defending communism. The issue is complicated but, to put it bluntly:
No, Timothy, communism didn’t fail in Eastern Europe because it was implemented wrongly. This is a very complicated topic but the tldr summary is “It is a broken idea, it did not work and it will never work. The natural and logical outcome of any attempt at Marxism is a bloodbath followed by autocracy.”
That being said, communism isn’t the only way to achieve a more equitable society. You have social democracy (in Lennin’s words - communism’s greatest adversary); organized labour movements; collectivist anarchism; communitariasm, etc.
Communism, as applied in the 20th century, violently fought against or oppressed all of these movements and is incompatible with any of them.
Not to mention that in most countries nowadays orthodox communists have been hugely discredited for excusing the Russian war of annihilation against the Ukrainian people.
In conclusion, if you live in the USA or Western Europe and you are unhappy with how corporate greed has ruined society, don’t look to communism for answers. There are many other proposed solutions out there - go and research these. Communism is very well known, which makes it easily accessible to people who want change - but it is never, ever the solution.
It seems that this aligns best to my experience. Habits encourage you to do something and it kind of becomes easier - but not automatic. Definitely never automatic. E.g. with teeth brushing - I will not automatically brush if I am not at home. It may also be difficult if I accidentally fall asleep on the couch…
Nostalgia is huge in the eastern block. That’s a separate topic of discussion, all on its own.
