Joe, this is Derek, the author of the piece linked above. I think you make a good point. When I first heard Will explain "earning to give," a part of me considered it off-putting and radical, but I've come to see it as an expansive view of doing good, because I think there are a lot of people who (a) wouldn't be good at charitable work or (b) would be good at charitable work but are better at - and enjoy! - other work. For these people, it's inspiring to think they can make a huge difference, too.
There is always the question: What happens if you discourage too many wonderful, smart people from working at charities? And here, Will's answer would be, I think, that if that starts happening, then we should reevaluate the advice. But for now, I think, the earning to give philosophy carries tremendous upside for getting more people to think of themselves as essential contributors to charitable causes, no matter where they work.
