How can we ever say anything bad about Bill Gates?

Yes, it’s a tax write-off, but TEN BILLION dollars for children’s vaccines to save untold millions of lives?  How many rich people even think of such benevolence?  By comparison the United States committed 100 MILLION to Haiti relief, even though I realize it might become far more as a result of the military efforts and that many of the expenses will benefit the American economy as companies from the United States will be providing many of the supplies.
