The paper written was well thought out but not quite complete. For instance, total war had been around for centuries. Ghengis Khan would completely depopulate lands he over ran. Every man, woman, child, livestock and even pet would be slaughtered. Going farther back, Sun Tzu in his treatise "The Art of War" laid out the way to totally defeat the enemy. Japanese businessmen study it and follow it's tenets to compete in the market place. I have a copy myself and some of the procedures are quite chilling. General Tzu has been dead for 25 centuries, so total war is not new.
Lincoln was a Republican and southerners are mostly Republicans. So, they complain about Lincoln but follow his party. Then again, when I was growing up in the 50's and 60's, a Republican would rather "be dead than red". Now the right brags about being a red state.
Economic causes of the Civil War predated the tax refered to. The grounds for war date back to nearly the revolution to break away from Great Britain. Even when this was a young country, people wanted all sorts of things but didn't want to pay for them, just get freebies. Whiskey taxes were a major source of revenue for the country paying for defence and interstate facilitation. i.e. dredging rivers and such. The biggest rebels about the tax were the ones who benefited the most from it.
I don't particularly like paying taxes. If I'm not sure I owe a tax, I pay it anyway. The I.R.S. sent me a letter about my tax return this year. It seems I made a mistake and they owe me money. Had I owed them money, I would have paid it.
I get a lot from this nation. I am protected by one of the best militaries in the world. The police generally don't bother me. I drive on decent roads, not great but decent. I can travel anywhere in this nation without having to have my "papers" like Europe. If I want to start a business and ship across the country, I can. I love this country, warts and all and don't really want to live anywhere else. Vist possibly, but I'll always come home.
