Looks to me like if anything there's a preference to get out of the cities and the Megalopolis. The internet and its attendant benefits like telecommuting, teleconferencing, Skype, eBay, Amazon etc etc have made some of that possible.
Hmm, not sure which megalopolis in Nebraska and South Dakota or Mississippi you might be referring to.
I did it myself. Had absolutely zero to do with "red" or "blue" states. I moved from a light-blue state to a red state to a purple state; nowhere in my considerations for a place to live did any of that even register.
Of course not, it is the policies and their practical effects that draw a person or drive them away and the policies of blue states tend to drive more people off than welcome them other than black market labor.
Reasonable post, Pogo. I hope you keep that up but alas, I doubt that you are made in such a way as to do it.
