If you want to drag out the "Brave New World" metaphor, it's only fair to say that IVF is actually more of a step towards it than licensing. In BNW, there ARE no parents, it's a dirty word, not that only certain people can become parents. At the Hatchery in BNW, embryos are created using egg and sperm in a test tube- something now possible, that wasn't in the thirties. So if you want to cry foul based on Aldous Huxley's work, I don't think licensing is where I'd do it, because there's very little to no backing it up in the literature. Conditioning a fetus for a certain job with oxygen deprivation and alcohol treatment, soma, etc. This is more of a "how far should we allow medicine to go" question ala Frankenstein than an issue of who should be allowed to be a parent. I think, anyhow.
