I think the system is naturally starting to feel the pressure, albeit it took too long (and may have been expedited by COVID at that). Just look at the number of articles about a postdoc shortage that are cropping up in major journals within the last couple of years. The NIH recently had a "request for information" from late stage PhD students and early postdocs about what could improve their opinions about doing/staying in a postdoc. Anecdotally, many in biology are feeling the heat, and I've heard similar rumors in some other departments. That said, I don't really trust the funding agencies and department heads to do the right things that will actually improve the long-term health of the system. I think we'll end up with a shitty band-aid solution instead like giving postdocs mediocre raises. It could take a really long time for the system to truly crumble enough to force change. We'll see though, I hope things take a turn for the better in the coming years because certainly I know many PIs that are frustrated for one reason or another. If you get enough profs on the same page it could have some actual power.
