In your opinion is Economics science of wealth or it is a study of human welfare ?

   Definitely a study of human welfare! Otherwise, wealth for whom if not for the people? Numbers, statistics etc are supposed to serve human welfare. Economy is, it should be considered as, a deeply humanistic science. It is invented and developed to solve people's problems about living in organized societies using in the finest way all kinds of resources. Economy is the most important servant of human kind in the quest of relieving it from it's primary agony of surviving at first, and developing its skills in order to create progress and welfare.
