"If Illinois taxed retirement income in the same way as Connecticut and saw the same rate of outmigration among seniors, it would have lost 10,577 more seniors from 2012 to 2018. Connecticut’s heavy loss of retirees is likely part of the reason why the state is now reversing course, and is in the process of expanding income tax exemptions for middle-income retirees."
A largely unasked question is becoming glaring: Is Illinois doing all it should to use artificial intelligence to make government cost less and work better? So far, the evidence says no.
