I'm sure plenty of people will make this same point, but I can't resist remarking that I'll invest the relatively modest 'effort' required to avoid ever actually being out of pocket in this regard until I've had the experience of owning a slave MYSELF.
And I've got plenty of hard physical labor around here that a meat-headed slave could handle.
Then I'll pay. Not before.
And, if the bill is to be a high one, I intend to mistreat my slave accordingly...
If no former slaves can be located, then the whole issue should be dropped.
