Based on his other comments, I assume he was referring to the challenges of finding the right places to spend money--places where the money will have the most positive effect. It's easy to give money away. Goodness knows there are endless people and organizations who would gladly take it. What's much harder is knowing ahead of time what impact a given donation will have. Or, to put it differently, knowing how effective a charity is at advancing its stated mission.
