It is a long-held perception that America is a nation where the government typically stays out of day-to-day business activities.

Even before recent implementation of massive interventions meant to stave off financial calamity, the federal government directly or indirectly provided significantly more credit than any of the country's largest private sector banks. And, of course, the government's credit.
