I wonder what the endgame is. What will happen in 20 years time? One option is that immigrants will pick up the baton. Old childless people might complain about immigrants from XYZ yet pay them for support. Perhaps other jobs will likewise be filled by people emigrating from poorer countries. Another is the same, but the economic growth will slow in these aging societies, and the rich aging countries will turn into poor old countries, without the means to attract immigrants. For different reasons, but the UK labour market is really struggling, as since Brexit it is harder to attract migrant workers in sought after professions. Why should you go do menial jobs in the US if India or Vietnam or Albania is booming, fuelled by healthy demographics, and the US is getting poorer? These now-old countries will sell off their economy for support, basically, a bit how the UK has been selling off bits of it to sustain cash balances. Or go without young hands to do the work, and implode in slow motion. Maybe having children will again become net positive. But if course the lead time on productive humans from scratch is very long.
