Mark Zuckerberg donated 100 million dollars to Newark public schools a few years ago, and they ended up no better for it (and arguably worse off). Here's a great article on the topic -- http://www.newyorker.com/magazine/2014/05/19/schooled .

The main reason for the failure of the donation to create positive change was that the community wasn't engaged at all in the reform process. The first time Newark students and parents heard about the donation and the accompanying "reforms" were when Zuckerberg announced them on Oprah.

I completely agree with your sentiment, and wish philanthropy wasn't seen as an unmitigated good thing.
