The Abyss Grows
The United States our founding fathers created was very limited in the powers ceded to it by the States. It was deliberately kept small and thereby subject to the will of the people. Their experience with the British had made the people wary of big government. Their independence was hard won and they were not about to give it up to a government so large and powerful it answered only to itself. This simple government worked well enough for a while. They even fought a war with the Barbary Pirates and another war with Britain in 1812 and one with Mexico in 1847. With the exception of a few naval battles, these were fought wholly by the Southern States while the North refused to fight. Even as Washington was burned by the British the North refused to send their troops into battle. (It seems the Yankee sense of unity was self-serving from the start.) The U. S. army that fought in Mexico did have a few Yankees in its' ranks.
As the "Union" grew with more States being added, the New England States saw their power being diluted by numbers not firmly in their control. (That little fish syndrome again) More States meant less influence for each individual State. The New England States even went so far as to try to give away to Spain all the lands along the Mississippi River to keep the only trade routes through their ports. Of course that failed, but it shows what lengths the North would go to in their greed and ambition. Having failed, it then became necessary, in their eyes, to concentrate more power in the central government while, because of their large population; they still held considerable power there. The problem the North faced was that not everyone wanted to abandon the ideals of government of, by, and for the people (regardless of the claims of Mr. Lincoln). The "States Rights" advocates wanted to keep the majority of the power in the States where it was subject to the will of the people, while the business community and "social reformers" of the North (commonly grouped together as "Radicals") wanted the power in the central government where they held power. (I still have a problem understanding the mentality of people who think a "national" government can handle regional or local issues better than the affected people can. Perhaps, if the people were automatons from their mold of "correctness", then this might stand a chance. However, this is not the case, and I pray it never will be. Still, so many people believe, or are duped into believing, that the Federal government can solve all problems.)
