Clearly you understand the connection between slavery and money. Since you went to the trouble of looking up some stats, perhaps you looked up what they did? Some grew tobacco, some grew indigo, and various other stuff, but I doubt tobacco or indigo would grow any better in the territories than the main crop of cotton.
But according to you, cotton was "the only thing making slavery profitable."
The truth is that slaves did everything from construction labor to industrial work to waiting tables in restaurants, and there's no reason to believe that everyone who owned a slave who worked in these areas was losing money on the proposition, or to believe that as the country expanded westward, new ways to utilize slaves would not have been found. Your constant insistence that everything that could have been done with slaves had been found, that cotton and other plantation agriculture was it, and there was absolutely no other thing slaves could do is without foundation.
