I think a FReepathon Lotto would be a great idea - would be quick and fun!
Another approach for the IRS could be a Lotto. No tax avoiders - just millions of willing participants.
According to http://www.lottoreport.com/mm03sales.htm sales for last Tuesday's prize were $210 million. In a typical half week the federal government spends about $40 billion. About half of lottery sales are spend on the prizes so you would need sales about 400 times the current frenzy level to fund the federal government.
