Oh man, give it up. There was no tax on exports. Does your cotton pick’n brain understand that fact. I’ll say it again louder.
There was no tax on exports. The South did not pay 72% of taxes.
You can stop trying to pretend there is a difference. You just can't stand the fact that the South was paying the bills, and the North was mostly riding for free.
A tax on imports is the exact same thing as a tax on exports!
You don't get imports without exports to pay for them!
How about you stop denying reality and explain how the North got it's hands on the money *IF* they were the ones buying the imports?
It could not be done without taking it from the South somehow.
