...we have arrived at the point where numbers just can't be comprehended anymore. This week, outstanding world derivative were declared to have reached the 1 quadrillion mark. Commentators lately -- e.g. NPR's "Planet Money" broadcast -- have struggled to explain to listeners exactly what a trillion is in images such as the number of dollar bills stacked up to the planet Venus or the number of seconds that add up to three ice ages plus two warmings. A quadrillion is just off the charts, out of this world, not really subject to reality-based interpretation. You might as well say "infinity." We have flown up our own collective numeric bung-hole.
The number problems we face are now hopeless. America will never be able to cover its current outstanding debt. We're effectively finished at all three levels: household, corporate, and government. Who, for instance, can really comprehend what to do about the number problems infesting Fannie Mae and the mortgages associated with her? There's really only one way out of this predicament: to get ready for a much lower standard of living and much different daily living arrangements. We can't wrap our minds around this, so the exercise du jour is to play games with numbers to persuade ourselves that we don't have to face reality. We're entertaining ourselves with shell games, musical chairs, Chinese fire drills, Ponzi schemes, and Polish blanket tricks (where, to make your blanket longer, you cut twelve inches off the top and sew it onto the bottom).
