I can say the same about cities borrowing money to finance infrastructure projects, but I've yet to see a political comment grousing about how a city's budget woes come solely from billions of dollars of 10-year old debt that has to be serviced.
King county just voted to take on 1.7 billion dollars in debt to renovate a county-owned hospital. Ten years from now, nobody will be talking about defaulting on it, but I fully expect them to be talking about defaulting on pensions.
