you have an incredibly bleak outlook on the "purpose" of a life. The slave is bred for the purpose of toiling for their master their entire life, does that justify anything? Hell the only reason the worker gets a wage is so they can work for the capitalist. The only reason people get maternity leave etc. is to breed more workers, that's your purpose in life.

Only the oppressor has a free choice in their lifes purpose. Well, somehow they always choose to oppress more so who knows. At least we have that old debate finally sorted.
