A trillion is a thousand times that: greenbacks piled an entirely inconceivable quarter of the way to the moon.
However, a trillion dollars -- a figure once so abstract that it appeared only in long-term Social Security projections -- comes up like crocuses these days.
• U.S. households lost $5.1 trillion of their worth in the fourth quarter of last year, the Federal Reserve reported Thursday.
• The world's billionaires lost $2 trillion last year, Forbes magazine reported Wednesday.
• Then there's the $3.6-trillion federal budget proposed for 2010.
• And its projected $1.2-trillion deficit.
• And $1.2 trillion in derivatives that ward-of-the-state American International Group insured.
