So far, there has been no industry that just continued making high margins over decades without any cut backs. I doubt tech will be the first one.
As tech can't print money, these salaries must come from somewhere. And at some point those sources won't be able or willing to provide it. Maybe that's a soft landing, maybe harder. I don't know but as I said previously, I'd be surprised if tech's the first industry in centuries that channels wealth into the hands of few (including SV landlords) without any consequences.
Yeah, that's what I doubt. SV is not the tech industry as a whole. The average salary for a software developer in the US is less than half than that, and if we removed those top outliers, it'll be even less. So I'm skeptical that this is out of the ordinary; doesn't seem that different from other well-paid white-collar professions like lawyers.
