Just because cities like Chicago are financial centers does not mean their their GDP "contributions" are meaningful. They don't actually produce anything worthwhile except for wealth for financial firm leaders and their cronies.
The bottom line is that good portions of these Democratically-run cities are violent crime cesspools. The white-collar financials guys in these cities are just another type of non-violent thief.
Please tell me you actually pulled some little house on the prairie stuff and built your own log cabin with a bunch of saws and mallets.
Well did you?
