I'm from a country with a demographics falling off the cliff, like Germany but worse, and just like Germany, housing prices (where jobs are) have went nowhere but up at a steep rate beyond wage growth, because housing is not a fixed pie for whom now less people are competing due to increased deaths vs births, because for a few decades now, it's no longer just people competing for housing against the other people, but piles of money competing against other piles of money, and the bigger piles are winning(aka investors).

If you expect housing to get cheaper because less babys will be born, you'll be in a rude awakening. If you want housing to go down you need to decouple it from investments because otherwise, all the levers will be pulled by the governments and banks to make sure that line only goes up regardless of demographics. "Too few babies are being born? No problem, we'll just market those houses to foreign investors. Problem solved. Line goes up now."

To add salt to the injury, SBB (the federal railway company) entered the real estate market and rents exclusively. It feels like a government sanctioned way to keep people out of the housing market.
