Slavery is a non sequitur here. Under the circumstances you might suggest “I will pay you below minimum wage” or “I will pay you nothing, but provide housing on my plantation where you work.” But so long as they have the right to walk away at any time its not slavery, and there’s nothing in the setup that justifies that loss of liberty. Your hypothetical situation is an argument against the minimum wage, not pro-slavery.
