You are correct that the "ideas" of Jefferson resulted in the bloodletting imposed by the Slaveocrats' attempt to destroy the Union and constitution. Fortunately, those ideas were so half-assed that they were inevitable failures.
Southern insistence on States Rights was one of the major reasons it lost. The states of the Cornfederacy were incapable of operating together as a nation and thus, dissapated much of the little strength it possessed because of this incapability. Hamilton correctly rejected a radically decentralized power and an agriculture-based economy understanding that such would never succeed in a contest with a modern state and a modern economy.
His understanding of the basis of political power was most fully validated by the results of that war and the growth of the world's greatest nation using his financial system.
ROTFLMBO!!!!!!!!! Would that be the same 'system' that has this nation falling apart at the seams? Tell me one part of Hamilton, Clay, and lincoln's 'American System' that has worked. Wait, it's the Federal Reserve, isn't it? No, the Fed Chairman sneezes and capitalist Wall Street drops 200 points. Talk about govenment control of the economy. No, no, that can't be it. Wait. It's the infrastructure. That's it!! All the roads that the government built for us taking 4 times longer than necessary to build the roads? No, no, because the owners of the Union Pacific did that so much it bankrupted the company and cost three to four times more than other railroads just like it. It's the social programs!! That's it, the social programs!! They take care of us and rape us of 20 percent of our income just for Socialized Security. Wait, that's going broke too!!
Maybe you could point out to me what part of the 'American System' Clay, Hamilton, and Clay's lackey lincoln envisioned that actually has worked?
