Why can't a US state default, but a EU state can?
US or EU states are sovereigns which cannot go bankrupt. US states have defaulted in the 1840's, but in most of those cases creditors were eventually repaid in full. (I'm not 100% sure, but I believe that Indiana was an exception with regard to costs incurred building a canal system) The best modern example of a true near-default was New York City in the late 1970's. Although New York City isn't a state, the size and scope of its finances is greater than many US states. What happened then in a nutshell: Basically, a default of a major state or a city like NYC where creditors took major losses would rock the financial markets and make it difficult for all states to obtain both short and long term financing at reasonable rates. That's why these entities get bailed out -- if Greece or California really collapse, it will likely create a domino effect that will have wide reaching effects.
