Go back and read post 493. You asked for help and when given, you did not bother to read it.
You mean the one where you say, "As for the cotton ports themselves, they did not crave enough imports to justify packet lines until 1851, when New Orleans hosted one sailing to Liverpool"?
And yet, despite not craving enough imports to justify regular shipping, the south, with one-quarter the free population (and I think even you will concede that slave didn't consume many imported goods), somehow paid the majority of the tariff. Is that right?
