A lot of people are managing through a combination of choices that basically amounts to accepting smaller living spaces, longer commutes, or both. You're seeing the remote work angle play out exactly as you describe - folks are realizing they can take a job paying decent money but live somewhere their paycheck actually stretches. Some are doing the multigenerational household thing again, which was way less common a decade ago. Others are just spending way more of their income on housing than financial advisors would ever recommend, which obviously limits everything else.
The sustainability question is the real one though. You can't have a functioning economy if people are priced out of living anywhere near where the jobs are, or if they're all stuck renting in perpetuity. Some markets are probably going to see migration patterns shift pretty dramatically as remote work becomes standard for more industries. But in areas where that's not an option - where you need to be onsite - something does feel like it has to give eventually. Whether that's wage growth catching up, a housing correction, policy changes, or just people deciding they're done and moving somewhere else entirely, I have no idea. The current setup just doesn't math out for a ton of people.
