Well, one of the issues, is that younger folks look at retired older folks, and think “unproductive leech,” while ignoring wrecked hands, shattered spines, and cancers. I also know many veterans, and they provided a Service that I definitely benefit from, today.
Also, speaking only for myself, I live off of investments and savings, created from 40 years of living frugally and sensibly. Every few months, I have to chase off people that try to steal those savings. It’s not surprising, but is annoying. There’s a huge industry, based completely around stealing money from older folks (usually ones without the means to defend themselves).
Back when I was young, there was this rather silly movie, called Logan’s Run. Besides a brief flash of Jenny Agutter naked, it offered a vision of a culture that literally kills off anyone over 30. The interesting thing, was that the culture still had strategic vision, but that vision was supplied by a machine.
