Comment: Note in particular the last column in their about the ratio of pay-go rate to current contributions. That means how much more would have to be paid to honor pensions if the pension runs out of money, which is when the government becomes directly liable for pensions. Chicago's teacher pension, for example, would have to pay out about 1.5 times more than is currently being put into the pension each year.
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.
