It's the division of family because of the need to travel for work that leads to the decline. China is suffering a bit from its one child policy and is having to import workers in some areas while having poverty in other regions.
I'm in a similar precarious position, still renting after 20+ years, in a job with stagnant pay that is as of this year now paying less in real terms than when I started. The gap between rich and poor gets wider even if our standards of living get better. That said, the UN found poverty levels in Alabama to be shocking in a first world country, complete with hookworm infections that are normally only found in the third world.
The Eminians, in the city at least, seem to live very middle class lives. This could be the future if cheap renewable energy is available to all but we don't know about their rural areas. Once you strip profit out of energy provision, the only major costs are food and housing. Population control then depends largely on space. One assumes that, since their infrastructure remains sound they can absorb the additional population for a while. Some births might previously have been as replacements for those killed but other people of child bearing age would now be alive to have children that would never have been. If the number of survivors is roughly the same as all the people who die in the USA every year, that's a lot of extra people!
The issue of euthanasia is toxic to us because it's alien to our culture. In a hundred years our elders might be happy to be cooked and eaten by their families in the aftermath of the water wars of the Trumpocalyse.
