But the point is that although these people are described as "Wealthy New Yorkers" they~ like so many in the UK as well ~ are still not "native". They still cling to the moral codes of their countries of origin. These things, as I get tired of trying to make people understand, are considered normal in certain parts of the world. When these people come to the "West" and make their fortunes they do not change their basic beliefs, the ingrained values of their upbringing, and what are in fact their natural instincts. I promise you that they are, no matter what they have been coached to say by their lawyers, utterly astonished that we in the West cannot see that they have a right to do this because of who they are.
Never forget that slavery was in being long before England got involved in trading with Africans to buy other Africans from them. This situation is no different. The ones who had the slaves saw it as their right to treat "inferiors" in this way and that has been the way of it for centuries.
