I just started Rabbi Lapin's book, Thou Shall Prosperafter hearing Dave Ramsey recommend it over and over again. In the first section, the Rabbi makes a very interesting point.
You should try to make more money for the good of everyone around you.
For the most part, you can't make money unless you provide something someone wants. Making money is an indicator that you have provided good things for the rest of us. For example, I want to drive a car to work, so I bought one. When I bought my FredMobile, the seller made money. That was good because without him trying to make money, I'd be walking. Dittos for the food we eat, the clothes we wear and the houses we live in. All came from someone's desire to make money. Therefore, the desire to make money is good.
Hmmm. I like it.
