Oh, so now you do finally confess the truth, that slavery was not limited to cotton States and could well expand over most of the United States, if "properly" supported.
Well, bless your dear heart.
Getting truth out of you is like pulling hens' teeth, but it seems, on rare occasion, can happen.
Thanks for that!
You certainly project a lot more stuff into what I say then a rational person can wring from the words. I believe this map shows where cotton (and therefore slavery) would have stayed.

I have maintained all along, that the greater wealth flowing through the South as a consequence of independence would have eventually caused these other states to leave the USA and join the CSA. The Farmers could have shipped their grains and cattle to Europe down the Mississippi, and European goods could have flowed back up the Mississippi in exchange. Nobody would have had to pay the gouging rates of the North Eastern owned and operated rail road system that was mostly created with government collusion.
Look up the "Grangers" to understand what I am talking about.
New York would have lost money on this deal. Lots of money.
