I love this very simple but powerful visual comparison of the gambling revenues and the money spent on gambling addiction support programs.  The author is only trying to communcate one point, and gets his message across very stongly.  I believe it was done by Tim Broderick, from the Daily Herald.

Found on InfographicsNews.blogspot.com.  Looks like Chiqui Esteban is starting a series of visual comparison graphics over there.
