The problem with communism is it assumes everyone wants that same thing. There are some evil baddies that don't give a shit about anyone but themselves. They only care about the money and the power and are usually the ones that eventually become the leaders.
If someone can tell me of an actual communist country that has worked, I'm all ears. I'm sure you could do it on a small scale, because you can weed out the baddies. On a large scale though? The greeds will take over just like anything else.
It doesn't even need to be bad people at first. For example under a socialist society can you pay a teenager to mow your lawn? What about if you promise to help someone find a teenager to mow their lawn and take a percentage of the money? What if you do it a hundred times?
I have to agree. Maybe that teenager loves this idea because they're kind of shy. Uber, Lyft, Airbnb, etc., started out as exactly that, but then they became the greeds. Also, there are tons of small businesses that don't became complete assholes and have employees that live a good life. Capitalism can work, it's just having a heart attack right now.
