Same with finance, we could all live an upper-middle-class life with all the luxury, for one parent working in the home, if we were willing to live the same lifestyle as the 1950s. But life today is much easier than even then — and we’d rather pay more for that extra luxury than live the spartan lifestyle that would’ve been luxury then.
I think that's a bold claim. Many things that were cheap then are now unreachably expensive. Many careers that paid well then are gone. The converse is also true; many things that were unreachably expensive then are cheap now, but that doesn't mean that we can easily live such lifestyles if we choose to. Forgoing a cellphone and seatbelts doesn't make it easy to afford a bungalow! Nor is such a lifestyle even legal, in many cases. And you won't find a payphone to call your family. The world moves around us, and it's not a matter of choice to be pulled along.
This is just flat out untrue for a variety of reasons. People need to stop thinking of 1945-1975 as "the norm," it was a world historic anomaly that was a direct response to earlier events- the economy targeted full and fair employment to stop people from drifting to more extremist ideologies because everyone literally just lived through the result of highly unregulated capitalism for example. That was a large impetus behind Keynesianism and Bretton Woods, which was ultimately unsustainable and led to the broader global economy we have now- which itself seems more unsustainable by the day.
