One of the enduring absurdities of socialism and communism is that, in some strange fashion, wages are slavery. Somehow, trading your labor and time to someone in exchange for some good, like money, or a service that benefits you is slavery. It's abject oppression. They like to cite that if capitalists owned all the natural resources, they would employee people for next to nothing.

Never mind the fact that a) you still have to work even if you assume no ownership of any real property in order to survive and b) working for pennies provides a benefit to the worker: not starving to death.
