I’m realizing that you are an economic moron. And you’re nuts.
You have me about ready to give up. You don't grasp how the Southerners could cut off all revenue from the North that was produced by exporting Southern products to Europe?
You cannot understand how if the South trades directly with Europe, the North gets cut out of any profit or taxes from trade they are no longer involved in?
I don't know how it can be explained to you more simply. At this point I think you should just ask somebody on your side how the North gets cut out of direct Southern trade with Europe.
The Northerners at the time sure understood it!
