For those interested, Prof. Thomas DiLorenzo, an economist and historian, has researched the economic roots of the (not-so-Civil) War, and specifically into what motives Lincoln and his close associates expressed, in their own words, at the time. Mrs. Tec and I heard him speak in person about his first book on that subject, The Real Lincoln, about fifteen years ago. It is worth reading.
If I remember DiLorenzo’s figures accurately enough, at the time Lincoln took office, about 80% of federal taxes were collected from the agricultural South (mostly from the cotton trade), while about the same proportion were spent in the industrial North (mostly on public works improvements — rails, roads, bridges, etc) Southern states objected to the imbalance, but were perennially outvoted in the CONgress. Lincoln pushed for, and got the CONgress to raise those taxes — in some cases, trebling them. South Carolina refused to collect the new taxes,pointing out that they would ruin many planters (to the benefit of Northern banks, who would become the new plantation owners.) Lincoln threatened to send federal troops to collect, indiscriminately, any amount, or goods, from whoever might be found to have anything worth confiscating, and began to provision Fort Sumter, as for the invasion. The South Carolina Militia attacked the Fort, and the rest, as they say, is the history you learned in the Public Fool System, and on TV.
For those who find reading too much of a good thing ….
