What you and other students of Karl Marx always ignore is the fact that if company owners was not allowed to earn profit then there would be no companies founded, meaning that the workers would not have jobs.
I’m not sure that means companies wouldn’t be started and everyone would sit around doing nothing.
Capitalists are well known to collude to keep pay down and viciously suppress unions.
