Actually it's a hypothetical and it belongs to me. It's my imaginary situation and I declare that in it, there are no other good options.
You're welcome to press me as to the why, of course, but let's just assume that my slave-owner is retarded and cannot come up with any option other than starvation or forced labor. Then we can move on with studying the morality of it.
But such a situation doesn't occur in the real world, so why figure out the morality of a situation that would never occur? That would be like saying "In my imaginary world, no babies would ever be born unless women were raped", and somehow trying to prove the morality of rape by such a hypothetical scenario. It's just not really helpful.
He has no means to feed people, not without slave labor.
And I'm assuming that he would have to pay them in food, just as we hire mules to work for us and pay them in food.
Again, that's an impossible scenario. Even assuming he must have labor in order to have the means to feed people, he doesn't have to get that labor through slavery; he can get it through some other mutual agreement between free people, like "you do this much work, and I will pay you a potato". In slavery, he'd similarly have to end up feeding his slaves a potato for doing so much work, so there is no difference in his means between the morally reprehensible action of slavery and the morally permissible one of mutual agreement.
If you want to pretend your scenario really only involves those two options, slavery or death by starvation, then there is no moral option; both are still immoral actions.
(And, you don't pay slaves and you don't hire mules.)
OK. That's a fine opinion. How about killing another human being. Never morally correct, in your view?
The circumstances surrounding killing a person determine whether it was morally permissible or not.
But, what circumstances ever make rape right? Similarly, what circumstances could ever make considering another person to be property correct?
