I'm criticising capitalism. You assume any criticism of it is communist. You're stuck. Here's a position: if owning a human being is wrong then renting a human being with a wage is wrong as well. If one of the core tenets of capitalism was the abolishment of the wage system then I could get behind it.
Are people not allowed to sell their labor in any form or fashion they choose? If someone doesn't know how long a thing will take & WANTS to be paid by the hour are you going to tell them they can't do that?
