The underground economy is also a problem. It's much smaller, I guess, according to the anecdotal evidence out there, but we don't even seem to have a good strategy to address the problems of the underground economy. Maybe it's a little simpler to deal with simply because it's a domestic thing, and we're not worried about all the creativity or the international intrigue.
What strategy are you aware of in terms of addressing the underground economy itself, and would it be reasonable for us to consider the principles underlying that strategy?
