Noted welfare-state liberal: "Of course, we should be fiscally responsible"

But what are the lessons for America? Of course, we should be fiscally responsible. What that means, however, is taking on the big long-term issues, above all health costs — not grandstanding and penny-pinching over short-term spending to help a distressed economy.

Equally important, however, we need to steer clear of deflation, or even excessively low inflation. Unlike Greece, we’re not stuck with someone else’s currency. But as Japan has demonstrated, even countries with their own currencies can get stuck in a deflationary trap.
