This sort of thing has been going on for years, its not just a recent thing in the last decade. Princess Diana is a pretty good example of this. People have been exploiting other people for thousands of years.
I think its admirable that you feel that way these days, and I think its good for any of us to check ourselves before we blatantly exploit others and their misfortunes. The world is no more a hellhole today then it was 20 years ago, or 50, or 100, or a 1000. You've just become more conciously aware of the wrongness in this sort of thing thats all. And it speaks well of you and the kind of person you are.
I believe however that while feeling appauled by it is one thing, unless you take measures such as Johnd has mentioned, and become an activist in this regard then you really aren't trying to affect some fundamental changes in the way society interacts these days. I'm guilty of being a pacifist in this regard as well, and I really can't offer any solutions myself. I suppose though, all it takes is one really good leader to get people on board and to make a difference.
