Most beautiful women are going to want someone who is at least moderately successful and financially set. "Rich" is a bit subjective, but if you mean should you let the women you are seeing know you are successful, my answer is yes. It will get you laid more often. Women are attracted to men who are financially and socially connected. This doesn't mean to flaunt it in their face, but you can certainly "show" rather than "tell" them you are one of these movers and shakers.
Women aren't necessarily turned on by the money itself; they are turned on by the fact that if you have money, it likely means you have the qualities that every female wants in the man (leader, smart, financially savvy, etc.).
