Chicago (State of IL ) are both raising taxes both on businesses and individuals. It is not considered a business friendly state or city. I believe Chicago may be the only or leading big city when it comes to population decline. The state has lost population too. The city has made progress; about 70% or so of it’s student’s graduate high school in 5 years. But it is centrally located.
Foxconn just located in Wisconsin, near the Illinois border after considering Illinois. Workman’s Compensation laws need a revamp. Moody’s rates Chicago bonds non investment grade.

I’d be very surprised if AMZN chose Chicago.
