The mental parasites—the imitators who attempt to cater to what they think is the public’s known taste—are constantly being beaten by the innovators whose products raise the public’s knowledge and taste to ever higher levels. It is in this sense that the free market is ruled, not by the consumers, but by the producers. The most successful ones are those who discover new fields of production, fields which had not been known to exist.
