Not in line with stats.

I remember reading one stat that only 8% of non degree educated Londoners under 40 are able to buy their first property. It's true tradesmen can earn a lot but then they are the 8%. It's like saying all lawyers are all guaranteed to earn £100k as a junior when it is only the US law firms who pay that so you should study law because of that.
Also what happens when interest rates stay high and it's a lot more expensive to take money out of your house value to build an extension. Demand would drop. I don't think most home owners who build an extension have £100k lying around!
The reality is that there is a supply shortage of housing. Historically, most people rented. There was a shift to the bottom half and working classes living in council housing. They were then allowed to buy it at a discounted rate, thus making them homeowners but they wouldn't have been able to do it without the discount. Now their children are unable to buy on the private market and have no affordable form of housing to live in while they save. Middle class people get help from their parents (mother in law bought a 1 bed flat in the 1990s with family help and some savings) and honestly husband and I bought at the same age (due to not needing to pay rent for three years at the family home). I think due to the cult of home ownership, some people have stretched and also due to income inequality (and other countries getting richer, hence more foreign money), houses in certain areas have become expensive relative to average incomes, but not relative to incomes in finance, law, tech.
And in such areas, 60k is regarded as a low salary and they tend to marry each other plus often have family money. However it is possible for such people to still be stretched as people assumed interest rates would be low forever and also the high cost of moving prompts people to buy bigger homes than they need.
