Europe declared war on Keynes, and Keynes is winning.

In the United States, Republicans lambaste President Obama’s stimulus package as a failure and insist on bone-crunching budget-cutting. If you want to know how well that works, come visit Europe — especially Greece.

Yes, Greece needed a wake-up whack and economic reform, but Republican-style austerity knocked the patient unconscious. Contrast the still-shrinking economies of Europe with the stirrings of recovery in the United States, and you feel lucky to be an American and a beneficiary of President Obama’s stimulus.
