That doesn't work if the extra income is produced by convincing people to donate to your charity rather than others, which I'd bet is often the case. Comparing your first and third examples, that's $9 million that might have gone directly to people in need through a different charity.

I do agree that people who work for charities should be paid, but the overhead needs to be reasonable. I don't know where the line should be drawn, but if a charity has far worse overhead than average, that's probably a problem.
