There is a fundamental moral difference between a man who sees his self-interest in production and a man who sees it in robbery. The evil of a robber does not lie in the fact that he pursues his own interests, but in what he regards as to his own interest; not in the fact that he pursues his values, but in what he chose to value; not in the fact that he wants to live, but in the fact that he wants to live on a subhuman level.

Ayn RandSo you think that money is the root of all evil? [...] Have you ever asked what is the root of money? Money is a tool of exchange, which can't exist unless there are goods produced and men able to produce them. Money is the material shape of the principle that men who wish to deal with one another must deal by trade and give value for value. Money is not the tool of the moochers, who claim your product by tears, or of the looters, who take it from you by force. Money is made possible only by the men who produce. Is this what you consider evil?
