Actually cryonics resembles progressive talk radio in most American markets. Those stations can't compete with profitable conservative talk radio stations, so they need private donations to stay on the air.

Cryonics also resembles Austrian economics, which requires subsidies from American businessmen like the Koch brothers to stay in existence because otherwise its professors can't find regular academic jobs and get their books published. (I call these professors "kept Austrians," analogous to "kept women.") Even then Austrian economists often have to give their books away, like Jehovah's Wtinesses or something, because nobody wants to buy them. By contrast, the non-Austrian economists who publish those Freakonomics books seem to meet a genuine market demand.
