Where you stand on the political spectrum, what you think of rich and poor people, and what you think about rich and poor nations and how they should act in the world, comes down, in my mind, to one single issue, and one only: Can wealth be created, or can it only be redistributed?
If you believe, as I do, that wealth can be manufactured out of thin air, then there is no limit to the amount of wealth you can amass. And since you are creating it out of thin air, there is no moral onus on making money – you work hard to create it and have stolen from no one. There is an expression for this: you earned it.
Indeed, since charity depends on excess wealth, excess capacity, the more you make for yourself the better off everyone else is. You can even throw charity out the window if you are so hard-hearted; the fact remains that you will spend that money to get the things you want, and the more you have the more you can spend. That money goes to other people. This interchange is called "the economy," and rich societies are rich because they understand in their bones the centerpiece of Capitalist thinking: Wealth can be created from thin air by human ingenuity and hard work.
