The drive to amass wealth exists only in certain definite social epochs. It is an instinctual drive which proceeds from the continual reciprocal action between external reality and the instinctual structure modified by it. The drive may be normal or abnormal in character; its absence in a person in our present society is considered abnormal. The motives leading to the amassing of wealth may be classified as: (1) rational motive; (2) the will to power; (3) the will to possess; (4) the sociological source. These motives are discussed in terms of the psycho-analytical theory of anal erotism and anal repressions, but with attention drawn to the sociological influences modifying these.
