And had they succeeded, the South would probably be like Bangladesh. There was not industry and the crops have been grown elsewhere --- at greater efficiency. And the entire world would have refused to trade with them due to the slavery thing. It would have been terrible and today you would be a recipient of CCF instead of the creator of the emerginf best Conservative thinkplace on the web.
Yeah, I'm sure England thought the same thing about the colonies once they won the revolution. Guess that shows you how much speculation and conjecture matters.
BTW, if they wouldn't trade with the South, due to slavery, why would they trade with the slave-holding North? Also, we didn't have anything to offer? Why is it that we were the #1 exporter of cotton? As for "it could grow elsewhere", um, where? Vermont? Germany? Sweden maybe?
...and the 10th Amendment is THE amendment to argue the point. The states did what the people wanted. You know, those rights reserved. No state voluntarily entered into the union without an avenue of exit.
