The US does a good job of selling the idea of living here and getting rich, though it does a better job of selling it to people who aren't already embedded in daily life in the US. While we have, perhaps, much lower numbers of extreme poverty compared to a lot of countries, as one of the richest countries, and growing richer by the day, we should have zero extreme poverty. The people with the will to fix our poverty lack the money and very few with money have no real desire to help the less fortunate.
