"And the rich get richer"

Two reasons which the rich don't normally talk about finances with others outside their immediate circle, particularly their own finances, or share their financial situation with others no so financially blessed, is basically because they feel that someone who may be envious of their good financial fortune/success will attempt to extract that good fortune from them in some way, or another. Another reason is that they have for the most part extremely greedy and don't want others to know how they have made their fortune and success, thus, eliminating potential competitors in their current field. Just my take on the true reason for hiding ones good fortune.
