I think it's partially cultural and partially economic. I left my home state (which scored poorly in this Senate report) because I couldn't get a great education in the state system, nor were there any prospects for the kinds of careers I was interested in (and there still aren't today). I love visiting where I grew up, and most of my family is still there, but the jobs I want are not and will not be there for any foreseeable future.

Seeing your edit, I can understand why you think it's mostly cultural rather than economic, but I definitely think it's both.
