I was at a party and a South African white expat whose family got enough money to pay for his decade of business / property stuff abroad I talked to was saying communism can't work cause then those poor wouldn't work and who would do the job no one else wants to do?

Seems any system is better than capitalism if one would look at him, who didn't work, who will not work and who doesn't do dishes and also left the party in utter chaos instead of putting his plates and glasses / cans into the sink (as you do if you are not do drunk or distracted).
