In a society where there are plenty of other well-paying jobs to be had, working at a nursing home won't be the popular choice. I expect the future to be interesting.
Personally, I'm preparing for a future where a nursing home isn't an option. Just in case.
It's common to equate old age with nursing homes and misery in the West.
Other cultures show that this needn't be the case at all and is - for the most part; there's still about 30% genetics involved - dependent on how you chose to spend your days. Less Netflix, Facebook, and convenience food, more exercise and healthy, non-processed food can get you much further than a billion dollars and medical personnel...
The health of that 80 year old is only relavent in terms of the amount of resources needed to move from the working class to the non-working class. The healther the aged, the fewer the resources. The higher the working:retired ratio, the fewer the resources.
What is to stop the adults under say 50 who have barely any capital at all (401ks, houses, shares, whatever) from saying "screw this, I'm off to $other_country where I don't live hand to mouth and have no future of retirement"
A country can not survive when 90% of its population are 80 years old, no matter how healthy or rich those people are, it means for every 10 hours an under-80 works, 9 hours is to produce goods and services for other people.
Now if the whole world was 90% elderly you might have a point.
Obviously a forever swelling population is not model we can or should try to sustain, but reaching some kind of replacement-level equilibrium is sustainable and is much healthier for workers' and retirees' economic health.
Any extra money from pay rises goes into spiraling rent costs cause by extra money from pay rises, which goes to those who own the rentable assets.
There is more than enough housing to go round. There is more than enough food to go round. There's more than enough beer to go round. Yet there are people working 100 hours a week sweeping floors that can barely pay for it.
There have to be better ways to distribute what's being generated (which is almost entirely from those ages 20-65) among the population without disenfranchising increasing numbers of those that actually do the work
Why? Because if we all start saving enough to retire without relying on growth, then that has a deletrious impact on the economy that makes retirement even more difficult.
This is because no matter how much paper you have, you still need people to grow food, build houses and run services once you retire. If there are more retirees than working people, you're in deep trouble. The average person simply won't be able to retire, ever.
