Mr. Cathy should get the jump on him and close all his businesses in Chicago and leave. All other legitimate busseinesses should follow Mr. Cathy’s example. Law abiding citizens should just leave. Give Chicago to the animals. Let them destroy each other.
Better yet, win a huge civil rights lawsuit and, as part of the settlement, demand Rahm’s resignation (or criminal prosecution). THEN announce that you’re closing all your stores and bailing. Leave town with some walking-around money in your pocket.
