It's mind-bogglingly evil and I can't believe people like you defend it on Hacker News of all places.
This is not the same as a company like Bob's Red Mill worker owned because Bob (who I actually met before he died) was a very benevolent person. Those people ARE lucky, but it's because they live in a capitalist society where they have rights to make choices.
The reality of communistic societies however is that it gets mismanaged by people in power due to fraud, power and control. The people in government also often decide to shut you up. If you speak up they WILL shoot you with a 15 50 caliber weapons for 1 minute.
Communism works great in small very focused communities of fewer than 30 people where you can - more or less- make sure everyone is doing the same amount of work, and you have the right to leave it if you want.
In capitalist societies you can own property, so you don't own 0, you don't own 1/100000000. Instead you have the option to buy 30 acres of land and build a house on it and have your own farm and do whatever the fuck you want on it - and ignore the state when you can - like I did.
