I understand how the "errors" comment relates to #8 & #9, but how does it relate to #10? Have you read the Wealth of Nations? What errors did you find? I suspect that you have been exposed Adam Smith's work via someone else's filter and interpretation.
Unlike Atlas Shrugged and The Communist Manifesto, The Wealth of Nations does not take a position and is consistantly observational throughout the book based on data of the time. Although Adam Smith is often noted as the father of capitalism, he is first and foremost a philosopher. It is clear throughout his works that he does not always agree with what he observes, but lays out the facts regardless. Most people latch onto the observations regarding self-interest in The Wealth of Nations and extrapolate it to mean that "greed is good" when in fact Smith is more focused on the notion that people have to do what is best for themselves and their families. A reading of his earlier work, The Theory of Moral Sentiments, expands upon his observations and helps balance the nuanced conflicts within each of us and society as a whole.
