Criticizing someone for doing good in the world while still enjoying their lives is a bit immature. As you've mentioned, we all have luxuries with our large screen TV's, cars, homes, etc.
Americans spend $60 billion on their pets every year: http://www.nbcnews.com/business/consumer/americans-will-spen...
Rather than complaining that rich people aren't doing enough, perhaps a lot more people can make more of an effort.
The point is that there are plenty of resources and it's just a matter of building up good organizations.
And no one is overlooking the fact that distribution is important. No one said that it wasn't.
There's enough food produced to feed 10 billion people.

My entire point wasn't to spell out how to solve world hunger, it was to illustrate that problems like this are within our reach. There's no need to ask "rich people" to solve every problem in the world.
