I think the folks that would get very excited about working on the problem of aging would not be excited about the amount of regulatory bureaucracy (trying to find a non-judgmental word to use there) that necessarily goes along with it.
In fact I think that the reason that so much innovation and wealth creation is concentrated in things which such dubious social benefit is exactly that it isn't regulated, because it doesn't matter. If it matters and is important, it becomes regulated, which slows and discourages innovation and the people who want to innovate.
