I agree on the first two, the third one I could strongly debate you on. Yes the North wanted higher taxes on the south. The south was paying the north and getting nothing back. Compare the roads, railroads and waterway systems just before 1860. The Northerners were sucking the south dry of profits and giving them nothing in return. One of the MAIN reasons for the war. Abolition was a minority. On the high end 10% of the north was in favor of abolition. Most Northern businessman couldn't condemn slavery because they were in the process of enslaving the Irish in their factories and factory towns. Robert Gould Shaw who led the 54th Mass., a black regiment, was a very very wealthy man. And you want to guess how his father made his money? You guessed, the slave trade. The slave trade made Massachusetts a wealthy state.
Indiana had strong southern sympathies in the southern part of the state. Indiana actually sent a Confederate regiment south. Many Indianans consider themselves southern before mid-western.
