That was not an assertion of mine. You asked: "And why were tariffs different in different cities? Did some states and local ports charge additional tariffs? That was the reason for the difference.
Sorry - I’m getting you confused with Diogenes Lamp, who claims that the War was all about money and the greed of Northeastern businessmen.

They did not because, financially and logistically, it made more sense to trade with New York instead.
