In the MultiEarth economic religion, to give away too much is wrong because it reduces one’s capacity to participate more fully in the marketplace which is the primary activity of our spiritual practice. If you give money away, it deprives you of contributing to the greatest good which involves investing as much capital as possible for the greatest return. Such investment is more important than charitable donations in measuring faithfulness in stewards.
Ever wonder why wealthy people (with some exceptions) give a lower percentage of their income and wealth than poorer people? A big reason is their religious devotion to the virtues of The Market.
