I went on a mission trip to Haiti, and yes, I think that if we had all pooled the money we spent on getting there, and just sent the money, some more could have been done to help down there. But those mission trips don't just touch the people there. They affect the people that go in deeper ways than the people there. The experience of seeing third world poverty in the flesh, and living in it, will change you in ways you can't imagine. Everyone I know that has gone tells their own stories of the impact it had in their lives, and the change in stirred in them. Little things, at different moments, hit you randomly when you're back. I've never felt noble, or all-worthy, or that I had done some great thing for humanity. It does make you see how trivial some of the things we put value on actually are. I wish everyone could get out of their life's framework and look at living and the world from some place entirely different from where we usually venture. It would help more things become understood, and lessen conflicts.
