Hmmmmm so his choice had a reason rather than just being knee-jerk racism? That's where the conversation gets harder because we are removing his right to run his business to what he sees as his best advantage. Do I agree with him? No, but I do see his logic and while it is discriminatory, I am not as sure that it is racist since he was considering the effect of race rather than dismissing them out of hand as unqualified due to their race.

If someone wants to dig ditches with soup spoons, that's up to him. Deliberately crippling yourself by refusing better tools is short sighted and the markets will respond appropriately. What do we tell people when they are making choices based on their own experience and they are the ones who bear the consequences?
