Within each of us there is a driving force, an inner need to be charitable and sharing. We also have a desire for hands-on influence over the actual charitable use for our personal resources.
The primary motivation and purpose of any private charity is really the accomplishment of the charitable passion of an individual. There are no good reasons even suggesting a wealthy individual should be prohibited from effectively managing a private charity. Rather, for the most part wealthy individuals should be given the reigns of a private charity, because they have the resources to actually get the job done.
The goal is to attain a compassionate life of balance and harmony, where an individual enjoys the pleasures of meaningful and fulfilled living. A truly significant life is a life of compassion.
