Probably not though. You don't want to cite an amateur with a Master's Degree in economics. Now if a Lawrence professor duplicates it, then it might hunt.
Another thing I notice about South Dakota is that wiki says this
"the Sioux Falls area, the larger counties along Interstate 29, the Black Hills, and many Indian reservations have all gained population."
I-29, the interstate seems to fuel growth. I hear that the west wants a four lane highway and a four year state college. I support both of those. A four lane highway from Salina through Ellsworth, Great Bend, Dodge City, Liberal and then down to I-40 at Tucumcari, New Mexico would do more for Kansas growth than an equivalent of money going to tax cuts for the rich. Since Garden City is unfortunately left out of this, they could be compensated, as it were, by expanding Garden City Community College and making it part of the University of Kansas system.
That's my alternative development plan. Instead of tax cuts for the rich, four lane highways and Universities.
