Here is a confession: I am a deficit denier.

To say this in respectable society is to be reviled as a self-serving rogue, worse than someone who denies climate change. Yet whenever I see a budget crisis — the U.S. falling off a fiscal cliff; austerity protests paralyzing Europe; Britain’s governing coalition tearing itself apart over missed budget targets -– I cannot resist the same conclusion: These countries’ leaders should take a deep breath, relax and stop worrying about deficits.
