Now that's funny, cause history has proven time and time again that the market, along with its innovative instrument, functions best under competition. It's classical capitalism. And it was precisely the element of competition that Lincoln wanted to eliminate by tariffs, thereby impeding the capitalist market's primary functioning agent.
Let the South win the civil war or let Lincoln die of cancer before taking office and the free-traders take over, and we'd be a banana republic with nazi flags flying over us.
I'm not quite sure how you reached that absurd conclusion, as it doesn't even follow coherently from your premise.
The North was the portion of American society that practiced ethnic cleansing - blacks were not allowed into most northern states, and the ones already there were despised.
