I don’t really think it can placed as a comparative argument, because under capitalism it’s more or less the exact same. Either you work or starve/jail.

For a more wholehearted answer. Under each ideology there is a perfect citizen for each of them. Any one ideology will fail in real life. Providing a rouge actor doesn’t disprove the ideology. Almost each country implements some aspect of each ideology in order to run smoothly.

Problem arises when a lot of people under capitalism feels left out, because only ruthless capitalism is rewarded. They try to find their communities online and now we are here. I’m almost certain that people here could create a functioning communist state. But you can’t create one, when people who are born in one are already part of it.
