Yes, but note that they have not done so in the 6-7 years since the Illinois SC ruled that public employee retiree (vested) benefits were untouchable. The state employee unions, the current state employees, and the still resident retirees under the pubic pension system are a Democratic voting bloc that will prevent an amendment from being offered. Crazy? Of course! But not a federal general revenue taxpayer responsibility. There should not be a cross subsidization of Illinois stupidity by taxpayers in states that acted responsibly.
“the Illinois SC ruled that public employee retiree (vested) benefits were untouchable.”
The Illinois SC had a conflict of interest because their retiree benefits were protected by this decision.
Illinois’s problem is so large that the state could become like Detroit in that real estate becomes worthless because property taxes become too high and there is no income to tax because all businesses have left. You can’t have a state made up of government bureaucrats, teachers, and welfare recipients.
