I don't think it's actually possible to be less skilled than Ayn Rand.
It's odd; I've heard these kinds of swipes a lot, and yet I really like Rand's fiction. It raises an interesting question: do tastes in literature vary so much such that whether someone is a great writer or unskilled (!) is wholly in the eye of the beholder? Or is there an anti-halo effect going on, where people think, "Rand's philosophy is wrong, therefore she must be bad at writing, too"?
Eh, her main literary flaws are the Author Filibuster and the use of Strawman Political villains and Mary Sue heroes. The definitive takedown was by Whittaker Chambers in the National Review in 1957.
Of course, other writers surely have written worse books than Atlas Shrugged, and not been so universally slagged, so there may be an anti-halo effect going on. That doesn't change the fact that Atlas Shrugged is terribly written.
Oldie but goodie. A piece of fiction describing how a computer system can do the job of human managers at fast food restaurants (scarily plausible), how this leads to a dystopia (slowly getting implausible), and how to avoid this scenario and reach utopia (give me a break).
