Narcotics: http://www.globalresearch.ca/index.php?context=va&aid=91 (estimated at 2-to-5% of global GDP which equates to about $1-to-2 trillion)

(Fitts says the US alone has over $500 billion in drug money flowing in, that was about 5 years ago. It's probably way more now.)

Oil: 30 billion barrels per year x $60 perbarrel = $1.8 trillion per year

That's not to mention the $2 trillion that the Pentagon has "lost."

Matt,
Thanks for the list. Its sickening to see the crazy waste in the world, and helps put it all in perspective.
