The Coming State Government Budget Implosion
State debt and unfunded liabilities have risen to an estimate $4.2 trillion, much of it in unfunded pension obligations. That is nearly six times total state tax collections of all sorts (license fees, property taxes, sales taxes, income taxes, etc) putting the states close to Greek territory. And I cannot tell from the methodology here, but $4.2 trillion likely underestimates unfunded obligations because many states have unrealistically high return expectations for their pension investment portfolios.
