This seems somehow unrelated.

It's not about scale, it's about balance. You can run a small an beautiful country with zero economy growth and zero decline, all in a perfect balance, and 70% of population younger than 65. Everything works out.

But when 50% of the population is older than 60, the picture changes a lot; the percentage of economically productive population is much lower, and the need to care for people who can't sustain themselves any more grows. Take a look at how Japan fares today.

Fair point, in hindsight it seems I may have thrown this book recommendation in under the wrong comment.

It's relavant to this Ask HN question at large as we very much need to move away from blind pursuit of unlimited growth in population, resource consumption, waste byproducts, etc. and address the question of how to live well within our means.

Aging population demographics is a challenge, but one that we must address and then move beyond to a move persistent and sustainable low term distribution.

As for the current situation, I am 60, my father was born in 1935 and lives here in the same town as I do. He takes meals on wheels to the older folks who aren't all that mobile (yes, he's almost 88, walks 10km per day, and maintains a 15 km long section of a 1,000 km long walking trail) which is indicative of the entire community which has the highest median age in this country.

There is scope to employ able older people to look after less able older people which gives provides purpose, companionship, and reduces the demand for younger pople in care roles, etc.

This is not a full solution but it is a partial path forward.

We'll we're going to have to learn how to deal with it.

At the start of the 1900s the world was set for a population boom and overshoot. We went from families having 6-12 children to 2ish children in a few generations. This is going to lead to those 'boom' generations having a far older population and there is not really anything that can be done about this unless you want your population to continue growing forever.
