I think Sam Houston's warning to the secessionists pretty much sums up this thread:
After the sacrifice of countless millions of treasure and hundreds of thousands of lives, you may win Southern independence if God be not against you, but I doubt it. I tell you that, while I believe with you in the doctrine of states rights, the North is determined to preserve this Union. They are not a fiery, impulsive people as you are, for they live in colder climates. But when they begin to move in a given direction, they move with the steady momentum and perseverance of a mighty avalanche; and what I fear is, they will overwhelm the South.
It's why the North won then and always has won, really. I say this as someone raised more culturally Southern than Northern. (And is DEFINITELY a "fiery, impulsive" person.) It's simply undeniable.
The people of the North are constantly underestimated by arrogant Southerners putting down "Yankees." To this very day. This is no less true of Florida vs. Michigan than any other Southern vs. Northern state match-up. But I find at the end of the day, the North almost always wins out in almost every way.
This doesn't mean I don't love the South because I do. Much more than the North on the whole, in fact. I just think it's rather foolish to deny all the advantages the North has over it. Michigan is simply a greater state than Florida, and certainly has been for most of each state's history.
