Capitalism without a modicum of Christian type morality can become as corrupted and oppressive as socialism.
It is interesting that the people who quote Adam Smith never bother to refer to the rest of his writings, such as ‘Theory of Moral Sentiments’. Smith was well aware that there would be those who could not function well in a capitalist system and said things about the poor that would make some of the acolytes of Rand rather uneasy. His book “THeory of Moral Sentiments” is not quoted as much as Wealth Of Nations...
“This disposition to admire, and almost to worship, the rich and powerful, and to despise or, at least, neglect persons of poor and mean conditions, though necessary both to establish and to maintain the distinction of ranks and the order of society, is, at the same time, the great and most universal cause of the corruption of our moral sentiments.”
-Theory of Moral Sentiments.
Much more in that book that is far from the partial quotes, so often taken out of context, that make Smith appear to something other than the moral philosopher he really was.
