Economics as currently presented in textbooks and taught in the classroom does not have much to do with business management, and still less with entrepreneurship. The degree to which economics is isolated from the ordinary business of life is extraordinary and unfortunate.
That was not the case in the past. When modern economics was born, Adam Smith envisioned it as a study of the “nature and causes of the wealth of nations.” His seminal work, The Wealth of Nations,was widely read by businessmen, even though Smith disparaged them quite bluntly for their greed, shortsightedness, and other defects. The book also stirred up and guided debates among politicians on trade and other economic policies. The academic community in those days was small, and economists had to appeal to a broad audience. Even at the turn of the 20th century, Alfred Marshall managed to keep economics as “both a study of wealth and a branch of the study of man.” Economics remained relevant to industrialists.
