The drive to satisfy the fundamental psychological needs is universal and explains also the puzzling behavior of the rich. For example the indifference of Warren Buffett toward the economic value of his fortune can be explained if we assume that it is not economic value but the signaling aspect of income that drives his work effort. Giving away wealth should also be seen as a manifestation of desire to satisfy the basic psychological needs because sharing is essential for strengthening relationship between people and thus fulfilling another of the three basic needs — the need for relatedness. Lastly the economic value of wealth is often used to buy goods and services that help people raise their position in social hierarchy — yet another manifestation of how economic value ends up being used for psychological signaling.
