This won't hold. Eventually, economic opportunities will open back up in the old industrial areas, and with the overall decline in the relative power of the United States, the wealth that has fueled the idiotic and wasteful economic policies of the last 20 years, ie suburban sprawl, will reverse themselves. People will tend back towards places where there is already a solid infrastructure in place, and where cities are actually, your know, cities. This will favor the Northeast.
I hope you're right. I'd love to see people return to places like MI, OH, WV, and PA.
