I hate this...yet am scared it's true.
Another notion I hate and are am afraid is true is that: even if corporations were prepared to cure cancer and take the hit, the state would be terrified of increased longevity, at least I think so.
Retirement age people are to the state, probably, what post-reproductive organisms are to evolution: dead weight that they can't "afford" to care about.
In these areas I think the incentives might be wrong, but we can probably too better somehow. No idea how that can be corrected tho... :'(
