There is a great disparity in the distribution of the world's resources. In fact, the richest 20% of the world’s population has 89% of the world’s wealth. But that's just Bill Gates and Warren Buffet, right? I'm "middle class" and am not one of the rich who "hoards wealth."
Check out the website http://www.globalrichlist.com/. You can go there and type in your annual income and find out how it compares to the rest of the world. A few caveats are in order, though. First, the website's data is from 1999, so it's a bit dated (but the most current I could find). Second, there's really no way to accurately determine what percentile anybody's annual income is, so the results should be taken with a grain of salt. Nonetheless, I think it help gives a picture of how rich we really are relative to the rest of the world. For example, if your income in 1999 was $47,500, you were in the top 1% of the world! That's staggering to me. Because we Americans are surrounded by extreme wealth, it's easy for us to forget how the rest of the world lives.
Hmmmm....what should I do once I understand how wealthy I am?
