I'm a big Dave Ramsey fan. He's against debt, in favor of saving and offers a great plan for getting rich. Getting rich is great, but that wealth has a purpose - helping others. My wife and I are working hard to pay off our last debt, our mortgage, so we can do just that. Being wealthy is a prerequisite for significant financially charity. As Dave says, poor people can't help others.
The same is true for nations. Zambia didn't develop the AIDS drug cocktails which changed that disease from a death sentence to a handicap. Ecuador didn't then distribute the drugs throughout Africa to try to bring an end to the AIDS-related misery and devastation. Dittos for all manner of other technological advancements which have improved and extended human life.
A common criticism hurled against America is that we consume a vastly disproportionate amount of the world's resources. Thank God we do or the rest of the world would be utterly screwed.
