Do you really think there isn't a better system than accepting that some other human out there is going to get more out of your work than you?
In nations with extreme abundance, it should be trivial to solve problems of homelessness and hunger. We have the means, but capitalism says "no, people must not be allowed to survive without working for others".
Why are we the only animal on Earth that pays others of its kind to survive and exist?
If capitalism cannot bring people up then its cancerous nature will naturally give way to unrest and change. Expecting me to know what that change would be, and what conditions would settle, is unreasonable.
