You might look at Peter Thiel's presentations on radical philanthropy or venture philanthropy for a similar view on how philanthropy at the institutional level might be changed. He's been arguing for years that the balance of risk and how money is put to use in the philanthropic world is well out of line with the goal of achieving meaningful results, changing the world rather than just propping up present situations, and rather than the very conservative way it runs now it should look a lot more like venture funding:

So that view seems to be spreading, which I think is a good thing in the long run.

Of course as I've argued in the past, I think that the best thing everyone could do with excess money is to donate to some form of SENS-like rejuvenation research to accelerate progress towards an end to degenerative aging. 100,000 lives are lost every day in really very horrible ways, the slow crumbling to a painful death, until we stop it from happening. It's just another medical condition, and the only think stopping the research community from producing therapies is money and the will to use it.
