Underground/Untaxed?

Interesting.

... the underground economy is surging, according to a still unpublished paper by a University of Wisconsin-Madison economist.

Unreported income in the U.S. has likely ballooned to as much as $2.25 trillion, creating a ratio of unreported income to reported adjusted gross income that is approaching the peak levels of the World War II era, the university said Monday

How'd he figure that?

There is an "astounding" $824 billion of cash floating around - enough to give every man, woman and child in the country $2,700 in cash, or $1,750 if you take out the roughly one-third of outstanding currency that's being held overseas, the university said.

Wonder how much of that is drug-money.
