I am quite surprised here because of the disparaging comments. It is true: in the past, nothing was given away for free either. Interest rates were high and prices, for example at the beginning of the 90s (parents of today's homeowners), were also high. However, building standards were already solid back then, and one should not speak ill of that. At least some insulation, massive walls. My parents, for example, have 2 bathrooms, etc. It’s better not to talk about the grandparents from the early 60s. Those were really simple houses that were put up, but they worked. The truth is also that while the jump from 1960 to 1990 still brought central heating, running hot water, etc., the jump from 1990 to 2020 is hardly noticeable. Whether the house is heated by a heat pump or a gas boiler? Whether the electricity is supplied by the nuclear power plant or by solar panels in summer? So what. The thickness of the insulation does not really bring any gain in comfort either; people simply could heat more for less money before. And it goes on like this. There are certainly some nice gimmicks, but nothing groundbreaking like the 1990 vs 1960 comparison.
It is also true that people lived more frugally in the past and especially spent less money on holidays and instead spent the time on the construction site. Generally, more personal effort was put in by oneself. But this was also easier because family ties were stronger and people were often still rooted in their hometown, which meant the social network was better.
Despite everything, one cannot sugarcoat the situation for normal earners and it is not as if no one buys the expensive properties anymore. They are bought, and with inherited money, not by double-income households, but by civil servant couples working part-time. Seen time and again in the social environment. Given one’s own income, one can basically forget about it in metropolitan areas unless one is already in their 40s.
How could it get better? More building land, lower building standards, fewer expensive legal obligations, and much more. Plus more personal effort again and less consumption. Will that happen? No. Less consumption is inevitable, because taxes (especially CO2) and social security contributions are rising. A better political environment for building? Hardly. At most, interest rates can theoretically fall again. Therefore better now than never, if it somehow works.
