EPI: Putting Public Debt In Context

I have been reading some papers from the Economic Policy Institute today after watching an EPI video of Paul Krugman, Jan Hatzius from Goldman, and some conservative dude arguing in a panel discussion whether Congress should extend the Bush tax cuts for the households earning > $250k.

I (of course) ardently oppose using our deficit to reduce the tax burden of the wealthiest 2% of Americans.  The economy is short about 11.5 million jobs.  We must use that fiscal deficit to generate enough demand to stimulate business investment.  And as this graph from EPI shows, we can totally afford to.
