Are people in the cryonics business making lots of money ?
No, most staff are volunteers or are poorly/modestly paid. Directors on the Boards of cryonics organizations receive no pay at all. Most people working for cryonics organizations do so because they want to be cryopreserved themselves. Cryonicists are building their own lifeboats. Although large amounts of money are received when a person is cryopreserved, some of the money must be used for cryopreservation expenses and most of the money must be held in trust for the cryonics patient so that income from principal can pay for long-term storage.
