A little bit of column A, a little bit of column B
so the nihilism is real and warranted, if they don't inherit at least a downpayment for a house from you while you are still alive, the jobs available - even for highly pedigreed people - don't provide the income for the downpayment, for the most part. they would need arbitrage with high paying work in a very low cost of living place, for a long time, or the same but coupled with a socioeconomic equal who also doesn't want any gaps in their high income employment.
many new-money parents want their children to prove... something... related to income and autonomy, which puts inheritance while living into "entitled handout" territory, instead of practical. while due to lifespan, any inheritance will only reach the child when the child is 60+ years old, where its impact to the utility and direction of their life is nullified, and it's just bean counting for the mere concept of "keeping money in the family" but doesn't give anyone a leg up in social status, partner selection, even where you own children's children go to school.
(note: if you actually are not confident in your retirement income and end of life care costs, then you are not parent this applies to. for parents sitting on big wins in real estate and other capital, it does.)
but the financial reality doesn't really support this slower moving culture. the share of people in the US that are both homeowners and married by age 30 has fallen to nearly single digits percents. Aside from marriage being less attractive too, many delay everything related due to being preoccupied with meager work and financial instability.
now that being said, the thing you are more familiar with, hustle, does still work. pumping earnings into an investment property somewhere less expensive does still work, only suboptimal because they would still need to be paying rent in the higher cost of living area. what's different is that burnout is just not valued any more. hustle culture itself is not valued, its nothing to brag about and a silent path one might pursue. while experiences are valued. entire generations of people watched gen-x and boomers delay gratification and saw their bodies fail by the time they reached the finish line. its seen as a cautionary tale, not discipline.
so yes, lots of people overcorrect into a defeatist attitude, but the incentives support it. normal jobs won't get them anywhere, high paying jobs also won't get them anywhere, the training for high paying jobs doesn't guarantee a high paying job either.
