Trying to solve a problem rooted in behavior with monetary rewards only perpetuates that behavior. Instead of saving the world, throwing money at it destroys it instead
For only ten dollars a day, a week or a month you can feed starving children in Africa. For only the price of a cup of coffee a year, you can make sure that no one in Kansas City ever goes hungry again. For just a third of your paycheck, you can subsidize a vast bureaucracy that will conduct studies on the best way to save the world and then come up with proposals that will only cost you half your paycheck.
