Why is there extreme poverty?

The reason there is extreme poverty is because of ignorance and greed, stemming from our modern society's ideals. People living all around the world, too involved in their own trivial problems, continually ignore problems outside their own community, whether purposely or not. Modern society, exemplified in the United States, has transformed into a greed strictin society which sole purpose is to achieve greater wealth and more possessions. Unfortunately, this expontentially growing society, teaching ignorance and selfishness, will only help those in need when they overcome this greediness, or realistically, it becomes benefiticial to do so.
