First of all, sorry for only now responding to the topic after the thread has died down. I still want to contribute something to the debate, as the author of the thread expresses the fears and concerns of the declining middle class (to which I also belong, by the way) quite well.
Why do people pursue a profession? Why do they complete a proper vocational training? Why do they become a functioning cog in the system? In Germany, this is not driven by pure necessity to survive, but by a promise of prosperity. If I do everything right, then someday I will be better off than my parents or at least enough for a cozy little house. This promise of prosperity. The American Dream of the Biedermeier is currently fading away completely. Whether the author now needs a house or not is another matter. Obviously, certain life goals can no longer be realized as they used to be. The dream of broad-based prosperity is over. As I said: I am in a similar situation. Surely we could still realize building a house and since we have children and still want more, that would at least still be conceivable, but the luxury our parents surely enjoyed when building can be forgotten by us. Therefore, for us, at present, the rational decision is naturally to buy future prosperity and look for used properties.
A few more words about the real estate market. When I drove yesterday with open eyes through the small villages in affluent BW, I noticed the extremely poor building condition of almost all houses along the streets. At least externally, time has stood still there for decades. I don't see the golden era of construction in recent decades here. Rather, the construction industry has made a fortune on single-family houses and residential complexes. In my opinion, this is a central problem. It's not about meeting people's demand for affordable and pleasant living space, but about making as much profit as possible.
I personally live in a former single-family house that was converted into a multi-family house with three rental units. At least two of the three tenants would like to buy their own property. Across the street an elderly lady has been living alone in an almost identical house for 20 years and spends all day trying to prevent her house from decaying. The likely outcome is that the tenants will go into debt over decades to buy or build something for themselves or remain renters. The old lady will eventually die. The heirs will sell the house at the highest price. Neither the tenants nor the old lady have gained from this situation. For the real estate market, however, it is good business.
And now to my personal opinion: The market economy is a great instrument for price finding if the buyer can at any time withdraw from the market through alternative actions. In existential areas (mobility, communication, housing, health) this is not possible. Accordingly, there will never be a fair price finding here. In my opinion, the market has no place here, as it only works one-sidedly to the detriment of the buyer.
