[lbo-talk] South -> North Cash Flow?

[Joseph Catron]

I was raised to vaguely understand that wealth in the United States
flows from the South (with its cheaper labor and more abundant natural
resources) to the North. However, I have no empirical basis for
believing this, and honestly don't know where to start looking for
something to prove or disprove it; maybe I just can't summon the right
keywords. Can anyone point me in the right direction?
