Over at Slate, Timothy Noah notes how much money from so-called "awareness bracelets" actually go to the causes they purport to champion.

In summary,

Bracelet Vendor Cause Portion that
benefits cause
Yellow "Livestrong" Lance Armstrong Foundation supporting cancer survivors all
Cinnamon Tsunami Relief Red Cross, UNICEF, CARE 1/2
Camo-green 7-11 USO 1/3
Light blue Awareness Depot Tsunami disaster relief
(unspecified charity)
1/10
Yellow Awareness Depot Support our troops 0

I find it ironic that the "Support our troops" bracelet doesn't actually support our troops. And is yellow really the right color to use to demonstrate support for the military?
