The only reason why de-population is a crisis is because the current generations have set up governments that depend on an increasing amount of workers to fund the retirement and health care of the previous 2 generations. In societies where people paid their own way through life, de-popualtion would not be a big deal.
It might even be considered a boon.
Well capitalist economies depend on growth. So depopulation would be a pretty big deal anywhere. It may be much worse in a socialist society, I agree.
And those who work until they drop are happier, too.
You'll never catch me in Floriduh wearing white shoes, white belt, white shirt, and sky blue pants lounging around a swimming pool.
That'll be the damn day.
