This is an unrealistic by definition.

No it isn't, this used to be the norm.

Unless a person inherits a house, it would take at least 10 years (probably 30) to fully own one.

Most people say 'have a house' in the sense of having owner's title of one, not of having their mortgage fully paid off. You're being ridiculously pedantic while ignoring the fact that it used to be massively easier for people to get socially established on a median kind of salary.

No, that was never the norm. I'm amazed at the extent to which people are looking at the past with rose-tinted glasses. There were certainly groups of people in particular places that were able to start quickly, but the norm was young couples sharing a single old beater and just squeaking into a house in their late 20s.

This is really like people looking back on the 2020s and saying "It was normal back that to make $250k out of college."

The luxury car at 26 wasn’t normal at all. The vast majority of people would never have seriously considered a luxury car.

I make many times the median income, I’m married to a doctor, I live in a low cost of living area, and I’ve never owned a luxury car, nor do I intend to.

It's been unrealistic for long enough. I was 26 in 2009. I did so happen to own a "luxury" car, but it was $8000 used. I wasn't able to buy a house until I was 36. Part of that was due to moving around, which brought with it different opportunities.

I still can't afford a luxury car. I guess I could finance one but that seems like a serious waste of money. We've got this funny blind spot around cars in general as a status symbol. You can get a fun to drive, older, sports car. If you do a lot of long trips then a larger vehicle might be more comfortable than a luxury model. Not saying anything against them but don't aspire to owning something unless you actually want to be sitting in it.
