“You may ask what alternative countries like Greece and Ireland had, and the answer is that they had and have no good alternatives short of leaving the euro….
“But the main point is that America does have an alternative: we have our own currency, and we can borrow long-term at historically low interest rates, so we don’t need to enter a downward spiral of austerity and economic contraction.
“So it is time to stop invoking Greece as a cautionary tale about the dangers of deficits; from an American point of view, Greece should instead be seen as a cautionary tale about the dangers of trying to reduce deficits too quickly, while the economy is still deeply depressed.
“The truth is that if you want to know who is really trying to turn America into Greece, it’s not those urging more stimulus for our still-depressed economy; it’s the people demanding that we emulate Greek-style austerity even though we don’t face Greek-style borrowing constraints, and thereby plunge ourselves into a Greek-style depression.” Emphasis added.
