Pensions: what is bad for GM is bad for the country too?

In the op-ed piece in the NY Times, Roger Lowenstein offers a compelling argument on a major reason why GM is on the edge of bankruptcy: retirement/pension benefits. He then ends it with:
Responding to the same temptation to offload expenses into the future, public employers have committed to trillions of dollars in future liabilities. In New Jersey, a huge pension liability has created a budgetary nightmare for the state. The city of Vallejo, Calif., burdened by police pensions, recently filed for bankruptcy.

Just as G.M.’s shareholders bore the burdens of its pensions, states and cities will have to force taxpayers to sacrifice in the form of service cuts, tax increases or both.

It is too late to restore G.M. to its former grandeur. But if public officials do not show courage by quickly funding the pensions they have promised to their workers, taxpayers will soon find themselves in an even worse crisis than the one G.M.’s shareholders are facing now.
