The South and the Civil War

I have made comments on this forum in the past about the coming of the Civil War with the intention of showing that the South had no reason to secede and by doing so only managed to bring down destruction on themselves.

Another example of this concept is one of the compromises from the Constitutional Convention in the 1780's.  The "three fifth's compromise" is always noted for his disparaging comment about African-American slaves; three-fifths of a person.  I think another way of looking at this compromise is the advantage it gave to the slave holding southern states.  The compromise involved the counting of persons (in a census) for purposes of representation in Congress and maybe more importantly in the Electoral College.  The south got votes for a population they considered property and not able to vote, hold office or have any privileges of citizens.  That plus the Constitution gave the south the ability to import more slaves for twenty years after the signing and then to continue to count slaves who were "bred" on the plantation, many times by the owners themselves.  This gave the south more electoral power than they deserved and a greater influence on passing legislation.  

My original position that the South had few real reasons to withdraw from the Union as they were basically in control of the debate over slavery and all other issues that may have derived from slavery.
