Well you decided on a war economy. That would be entirely based on credit. The data I gave you was for a peace time economy. Second, apparently you don't do any reading, or you would have seen the tariff rate that was legislated.
The tairiff rate was legislated? Well, duh. Same as up North. The confederate congress could have set it as high as they wanted to. But since you hold out the free trade zone stuff they would have had to find their money elsewhere.
