STEPHEN EIDE: The Blue-State Model Collapses in Connecticut.

Many Connecticut conservatives cite the adoption of an income tax in 1991 as the beginning of the state’s woes. Up to that point, the Land of Steady Habits had an inspired run, poaching businesses and residents from overtaxed New York. Connecticut governor Lowell Weicker, a former Republican who served as an independent, worked out a deal with lawmakers: Government would impose a spending cap in exchange for the tax hike. But the state never fully implemented the former.

After having been raised four times, the top marginal income-tax rate now stands at 6.99 percent, almost two points higher than the 5.1 percent in neighboring Massachusetts. The income tax has generated a flood of new revenues — $126 billion over 25 years, according to the Hartford-based Yankee Institute for Public Policy — but somehow state lawmakers neglected to direct adequate funds to the pension system. As a consequence, Connecticut’s state employees’ retirement system is funded at only 35.5 percent, one of lowest rates in the nation. Despite a slew of recent tax increases, state government now faces deficits of $1.5 and $1.6 billion in the next two fiscal years.

Anything that can’t continue indefinitely will stop, and debt that can’t be paid won’t be.
