I'm sure those charitable Northern merchants just sucked up that tarriff cost as a consequence of doing business. Those gracious souls, God Bless them.
Either that, or you might consider researching the effects of tarrifs on consumers.
I'm aware of the effect of tariffs on consumers. My point is that the south consumed next to nothing on imports. Had it been otherwise then 95% of the tariff income would have come in to Charleston, New Orleans and Mobile instead of New York, Boston, and Philadelphia.
But let me ask you. If you sign on to the claim that the south paid the lion's share of the tariff then what was it that they were importing? If your claim is that they indirectly paid that tariff in higher goods for domestic products then what domestic products did they consume in such massive quantities?
