First of all, Florida, Georgia, North Carolina, and Virginia all have GDP output higher than Minnesota (TN isn't far behind), so if you think that they are "not particularly rich states", then neither is MN.

Hell, even Hutterite colonies are getting grants to put up wind turbines. You need to get out of MN more.
