Nah, that’s just wrong. You can compare yourself in other ways than how much fake money you earn. Fun thing is: truly communistic society would mean easier work for most people.
And communism does work in small scale enviroments. Families, cooperatives, tribes. Sometimes neighborhoods.
This whole “Sounds great but won’t work” rhethoric is just what the ones that would loose their power in communsim want you to think. If you dig into it you will see, that there were and are a lot of efforts to discredit the idea.
