Eccentric and Lovable Historian of Politics and Ideas
Rand is being ironic. The novelist is revealing something about human depravity but it is not the depravity of businessmen. It is the novelist who is so depraved as to write for money and use the very market system created by businessmen to attack markets. For the sake of making a profit, the novelist is destroying the ability of everyone to live freely and work for their own profit.
