Wealth and success in any area of material endeavor are not virtues that become part of a person himself. There is no intrinsic value added to a wealthy person that a poor person lacks. People are basically the same regardless of how much or little they have. As the popular saying goes, "My wallet can be embarrassed from his wallet. But I myself will not be embarrassed from him."
Contrast this to spiritual matters, such as Torah study and doing good deeds, where the more we grow, the more we ourselves are elevated. Love Yehuda Lave
