I think King Solomon (or someone else, I'm not sure all the Proverbs were written by him, but I could be wrong) wrote about that in the Proverbs. That poverty is bad because it causes one to be dishonest and steal, but great riches were bad too, for some reason, I forget. But being just in the middle is the best.
Wow, that's some kind of theological ineptitude for you all, isn't it???
