I mean, that the larger the group, the more assholes you will find in that group. Communism works great for families, and households. They look out for and support each other without keeping financial logs of who owes what.

Try to do that on a country wide scale, and there will be people whining that they don’t have enough, or they do too much, or that others deserve less, and they will lie and cheat and manipulate their way into getting more and more and more.

It’s a great system, far too good for us stupid, selfish humans to ever accomplish.
