If we’re talking about diminishing the electoral impact of old people, maybe instead of “death panels” you could set up “vote panels”, where a committee of experts decides if a particular senior should retain the franchise.
Or just give everybody a palm crystal and eventually send them to Carousel. Renew! Renew! Soylent Grey is made outta old people!
Or just set them adrift on an ice floe. I’m only half kidding. I don’t think people who have no stake in the future should have such disproportionate influence in how we plan for it.
