Anthem, certainly dystopian, is at least a runner-up for Worst Book of All Time.
Atlas Shrugged also counts as dystopian although may depend upon how you feel about the managerial class: Having them all walk off the job may be utopian.
The Fountainhead, however, is neither utopian nor dystopian. It’s an ordinary novel about an architect so callously egotistical that he resorts to terrorism to show his displeasure at having one of his designs altered.
Ms. Rand’s sophomoric philosophy vibrates in sympathy with the American myth of the rugged individual, the self-made man, ubermench, or what have you. There can be no stronger indication of the moral turpitude of our times than the high regard accorded these turgid works.
