This is a tricky question. I don't believe in simply just blindly helping people, because I think most people are for a lack of a better word, scumbags and spoiled. Will you simply give it to the poor, where a large percentage of them are going to buy say the latest iPhone so that they can impress their friends. If you blindly give your money away like that, it's almost the same as burning it.
What I would want is to build something with a foundation, that will last for centuries, where those who care can better help themselves.
