It is all a question of attitude. If basic physiological and psychological needs are satisfied, then people lookout for other higher/lower needs like ego and self actualization etc. Beyond a point money can itself become a source of worry for all normal persons. But exceptions may be there when greed takes over one may madly go after money.Evidence of this is seen in all societies. At that stage some spiritual guidance may be useful but cure not guaranteed. Too much money when it falls into the hands of younger generation has also lead to bad influence and low morals. In end money can buy many things but happiness may not be one of them!
