There are schools of economic thought that suggest that economics is simply a study of maximizing utilization of resources: supply and demand, without a moral consideration. The Marxist and the Nazi would be proponents of this thinking. If we need to kill a few millions of people to achieve our goals, then that must be done, they would say.
While I was at the University of North Texas, we were taught that economics is "the study of decision making." I would suggest that decision making without moral consideration is incomplete.
Also, economic thought originated officially in the writings of Plato's "Republic" and those of his student, Aristotle, about 350 B. C., as they expanded upon their examinations of moral philosophy. As moral philosophy is the root of economic thought, it would seem preposterous to neglect the connection now.
