Interesting article.

But if you really really want to do more good, you also have to change the way you see people in need. This might involve buying a ticket to Sudan and seeing children face to face while they are starving to death.

So in the long run, your $5k trip to Sudan might do more good than giving a one time $5k donation to an organization, because by changing the way you think about starving people, you will have the urgency of actually changing your priorities. So you will literally work for those who die of starvation in other countries, and deprive yourself from buying useless stuff or entertainment in order to feed more children in Sudan.

... unless you're psychopath, of course. ;-)
