They must know that this whole big top is coming down soon -- and it won't be pretty in a welfare state like Illinois. There are a lot of people depending on the government for bread and board.
The fact that Illinois is a very "blue" state is one of the reasons I'm glad I left.
Places like Chicago and Rockford will be violent, chaotic hell-holes if the crap ever hits the fan. (I'm from Rockford, BTW)
Number one, people there don't have the same hard-working, self-reliant mentality that you find in the South. Number two, the cities are highly mixed racially, and that always becomes a problem in times of crisis.
