I really like Boone Picken’s Feeding Trough example about wealth. How it is not a matter of taking from someone else in order to become rich, that the feeding trough is only so big. Instead, thanks to capitalism the Feeding Trough is Infinite in that anyone can Invent something, or work hard enough and become rich. In that being Rich does not mean that you took from someone else but that you made NEW things that did not exist before (or improved things) and that helps to improve the lives of everyone.
The best thing about Money is making it and also giving it away.
