Interesting. Do you happen to have a breakdown on the types of Federal spending in each state?
I ask because I suspect that a considerable amount of Federal money spent in the South is defense related. IIRC, the majority of military installations are in the Southern states, as are a number of defense industries.
Taking advantage of a legitimate Federal function (defense) is not quite the same as taking advantage of illegitimate, overreaching Federal programs....assuming that is the case with the Southern states, of course.
Unfortunately, I don’t, and that’s something I’d like to see. However, given that the poorest states are also disproportionately in the South, I’m willing to bet the majority of the welfare money goes down there too.
