Automated Levies Trend Down

Automated levies took a huge dive in 2008. After skyrocketing for seven years the number of levies issued by the IRS has taken a deep dive.
In 2000 there were 219k levies. They more than doubled in 2001, to 624K and doubling again in 2002 to 1,283k in 2003. The trend continued with meteoric increases in the numbers of levies in 2004 when the number hit 1,680k. The IRS laser printers were smoking in 2004 when the numbers hit 2 million at 2,029k. 2005 saw another 35% increase to 2,743k. Entire forests were cut for the 3,742k and 3,757k levies sent out in 2006 and 2007.
But in 2008 there was a precipitous dive in the amount. The drop was as dramatic as the rise. There were 1.1 million less levies in 2008 than in the two previous years. The number was 2,631,038. What happened? Maybe the programers at the IRS got a little sophisticated. Were they sending out levies to bad addresses or employers from 8 years ago. Are they collecting as much money? 30 Billion in 2007 and only 24.8 billion in 2008. What is going on? Somebody clue me in.
