The posers out there that want tax payer money to go to their cause are the absolute stingiest when it comes to their own money. Their motto is "Someone should give money, but it's not going to be me." That's cowardice, phoniness, and should be shamed. The idea of the government giving out charity money is awful for the personal growth and personal connection that donors get when giving their own money, under their own will, not under the threat of government force.
For Bill and Melinda to commit to giving all of their wealth away to charity before dying is beyond noble.
Bill's mosquito release brings a very real situation to a mostly sheltered culture. Those I know that have gone on mission trips to poverty stricken countries all profess that the were forever changed by the experience. Gates unleashed a small jar of change on that crowd, and I do hope it takes root and holds.
