By: Mark Glennon* If a leading voice for Illinois Democrats and public unions on the legality of pension reform is correct, this is the consequence: No Illinois constitutional amendment, act of the United States Congress or Federal bankruptcy can ever, for eternity, reduce unfunded liabilities in our municipal and state pensions. Only voluntary trades made at the discretion of pensioners, which obviously can’t accomplish much, are permissible, he says. Statewide, those unfunded liabilities total $371 billion, according to recent data compiled by the Stanford Institute for Economic Policy Research and based on more accurate “market based” numbers.
