Really? Not even the fact that I quoted word for word from the chapter itself?
In 1860, the South imported $346 million dollars worth of products. Of this list of goods, $240 million came from the Northern manufacturers and suppliers, and imported goods sold to the South was $106 million.
You keep saying that. Others quote much smaller figures. And neither rises to the level of providing a large minority of federal tariff revenue, much less the overwhelming majority that you claim came from the South.
Regardless of what you think and “what others say”, the data is this:
