I was surprised to not find a comparison between those private charitable contributions and the money spent by nations all over the world on similar programs. Unless I am missing something, it would look to me like the Giving Pledge, all together, spent more money on the fight against AIDS in the last 10 years than the U.S. government did [0]. If that is true, then there are still the questions left of who spent money more efficiently, whether and which other uses of taxes are more important than the fight against AIDS, as well as the general philosophical question of whether we should allow a few individuals to control how a huge proportion of the resources of the world are used, and under which circumstances. But beyond all those delta-from-the-ideal-world questions, it is indeed a pretty huge amount of good likely being done there.<p>[0] <a href="http:&#x2F;&#x2F;kff.org&#x2F;global-health-policy&#x2F;fact-sheet&#x2F;u-s-federal-funding-for-hivaids-the-presidents-fy-2016-budget-request&#x2F;" rel="nofollow">http:&#x2F;&#x2F;kff.org&#x2F;global-health-policy&#x2F;fact-sheet&#x2F;u-s-federal-f...</a>
