I'm curious where you get this number.
Tariffs are essentially a sales tax. They are paid by the importer, who passes them on down the chain, where they are eventually paid by the consumer.
Do you seriously contend the South consumed 80% of imported goods on which tariffs were paid? If so, where did you get the number?
Most of my figures come from government documents from the period as well as many private collections of various family documents either held by the family and viewed with permission or housed in many museums across the South.
Tariffs are are a sales tax. If you are making furniture in NH, you don’t need to buy tables and chairs from France. If you have a foundry in PA, you don’t buy stoves from England. When nearly all of the shipping is owned by Yankee traders in Mass. those products from Europe never make it to the dock in NY.
If you don’t buy anything, you don’t pay any sales tax.
A quick look at the available figures on population will show you that I’m correct about the distribution of people across the country at the time. Representation in Congress being allotted by said population shows the South being at a severe disadvantage as a voting block.
I would go on but time is pressing me. The research is quite easy to do, hell, I did it.
I’ve read that with out the tariffs, North East industrialists would be out of business as the then super factories of England could produce and deliver equipment cheaper. Further, this would cost Wall Street investors who financed the North East factories. New England/New York economy would collapse.
