This might sound like a complex or intricate statement, but it is deceptively simple.
If you graph housing price over time, is the graph increasing or decreasing? If it is increasing then housing is a good investment and therefore becoming less affordable, if it's decreasing then housing is not a good investment because it is becoming cheaper and therefore more affordable.
It is supply and demand. As long as supply is restricted homes will increase in value, and if homes increase in value, that's a pretty good indicator supply is not increasing.
This is in aggregate, of course.
Homeowners want their homes to appreciate in value, and many, particularly old people, are using homes as their main vehicles of investment, so of course any policy to increase supply is bad for them. This creates an incredibly powerful political force.
How do you fight that political force?
Some cities obviously have no room to expand so the only option is higher density. Where that is not the case, build single family homes en mass until anyone can afford one. I’m a home owner now but would rather see people be able to afford what they want than to see my own 2x4s appreciate.
When I was in school most of my friends lived in the inner suburbs and had good access to public transport so they could all meet up in the city and do things, while I was further out in an arguably richer area but without public transport so I was stuck inside missing out.
If old homes were somehow better and more desirable, they could theoretically be both. But homes aren't like comic books or magic cards: newer-built ones are generally better in quality, often dramatically so.
Being a good investment is a different question and really comes down to your alternatives. You need to sleep somewhere, and renting includes many overheads. Depending on how you value your time and what skills you have managing your own home can be worthwhile or a waste. A carpenter may use their downtime between jobs to improve and flip their houses while a doctor is wasting time calling people for even the most modest repairs.
Mathematically this isn’t true, as housing (even owner-occupied housing) pays a dividend [0]. So a house whose price tracks inflation (0% real price return) that pays a 4% dividend in net operating income still has a respectable 4% real return. Juice that return way up with a fixed-rate mortgage and you still have a great investment without home prices racing past affordability for normal people.
But that’s just the theoretical perspective. I don’t know if housing can be a good investment and affordable in practice.

Your house might pay a dividend, but it has immense maintenance cost.
If the dividend from your house, on average, is enough to pay this cost, we’re in this hellscape.
My wife is the chatty sort, so she'd ask them about how they could afford it and they'd always be leveraged up to the eyeballs. The cheap credit hog has been a complete disaster, and when the rates inevitably rise to where they should be we're going to see a lot of idiots with a lot of unbacked debt defaulting on everything.
Make it possible to build more then the market should eventually correct, but the financial squeeze will continue until the market has plenty of supply as often referred to by economists as market clearance such that demand is saturated at all levels.
There's a considerable difference between the loan payment with a big down payment and good credit versus bad credit and a low down payment. That difference can essentially turn an unaffordable home purchase into an "affordable" monthly rent.
On a 300k house, the difference between 5% and 20% down results in around a 400 dollar difference per month in a mortgage payment. That can be a pretty big difference maker for a lot of families.
5% down on a house like that is also 15k. That's a significant amount of money to save for a lot of families.
There are other relevant factors here as well, but this is certainly a significant one.
This kind of market-based intuition doesn't always work in a constrained market like housing, where what kind of housing you're allowed to build, how much of it, or whether you can build housing at all, is all heavily determined by local regulation.
In the US, this isn't true. It's not uncommon for property to rent for higher than the cost of mortgage, taxes and insurance. That is, be profitable from day one (assuming 20% down).
People complain about being able to afford a mortgage but not being given one. Or not being approved for a monthly payment of Y and instead paying Y+X a month in rent.
In China, the situation you described exists. Have no idea about in Europe.
Seriously... Just a few years ago, banks were giving you loans for like 1 - 5 percent down..
The time it takes for prices to reflect reality can take far far longer, in some cases, than anyone is comfortable accepting. There is no fundamental law that says things need to happen at the speed of convenience.
Certainly over the course of human history some sociopolitical or economic arcs took multiple human lifetimes to play themselves out.
Landlords couldn’t care less about affordability, so “the market” is very happy to make money by pushing people into survival mode.
(Affordability in housing is often measured as being up to 30% of income, whereas people can survive by sacrificing everything else — including heat, and food — spending up to 80% of their income on housing. That gap is where the increases and profit of the last decade have been coming from.)
But the average income of folks in SF is really high, because people without very high incomes can't live in SF!
That's bad.
I have this theory (I wish I could think of a way to easily prove it right with some kind of cherry-picked statistics/data but I'm not confident I'd be able to) that we've finally reached a point (I'm sure it isn't the first time in history but I don't know a lot of history) in "late-stage capitalism" that the top 20% don't mind paying/can pay/will pay/are willing to pay/compete with each other to the point where the bottom 80% can't keep up.
My source is, I tried to buy a house semi-recently. All of the typical stuff you read. Lots of demand/competition. Middle class stuff. The houses sold for what it sold for because that's what people are willing to pay.
Whether it's because the couple who won the bid had bought a $300k house 10 years ago and it doubled and they had $300k extra in funny money equity fall out of the sky is almost irrelevant because it puts them in that "20%" category. Once you are in that category (in my mind), things like "I should drive a Corollla to be efficient" go out the window when every stop light is people who can comfortably afford $80k BMWs without blinking an eye. "Who would pay that?! You can get a good used car for $20k! Blasphemy"
I see it like this:
If a house is priced for $600k but your gut (bias based on historical data) says "it was just $400k not too long ago, it should be worth $400k! this is madness", but then the market moves on and leaves you in the dust (and that $600k house goes from $600k to $700k and beyond), it's just upper middle class people paying (hopefully) what they can afford/are willing to pay.
Would you agree if I said the problem isn't really the billionaires when it comes to why middle class hard working people can't afford a single family house, but instead it's people making $200k/yr+?
However, the reason we are all able to earn so much is due to the ruthless pursuit of capital further up the market. The only reason we are able to earn so much is because billionaire business people decided that the best way to maximise their company value was to take the not-innovative option and pay lots of people huge amounts of money.
I think irresponsible is probably a poor word choice here (in my opinion) just because it leads my mind to think the assumption "why aren't they entitled to spend the money they earned the way they want to"
But instead of splitting hairs there, I'd be more curious to potentially partner with you in the effort to accurately determine whether the effects of the group we are specifically discussing are actually having a sizable impact in "harming" (preventing) the groups below them from being able to purchase a house
