In order to understand any economic study as a whole,one should read these volumes to excecute decision making flawnessly by knowing exactely the morel consequences and economic effects this may have on those involved by it for the well being of all.
Therefore, one can not look or exercise the difficult art of business decision making in the future without knowing the historical past of the economic foundations on which the modern art of guiding any type of decision making is based.
Adam Smith's enormous authority resides, in the end, in the same property that we discover in Marx: not in any ideology, but in an effort to see to the bottom of things.
It was Adam Smith who first established economics as a separate branch of knowledge, and many would say that his work has never been surpassed. The Wealth of Nations, which appeared in 1776, is the definitive text for all who believe that economic decisions are best left to markets, not governments. At the heart of Smith's doctrine is an optimistic view of self-interest. Though each individual seeks only personal gain, the collective result is increased prosperity, which benefits society as a whole.
