Is there a fix for this? Is it just a payment of loans issue, or is it a working conditions issue or is it a lack of interest issue? Or is it some combination of the three, or another, unknown thing (or a known, unmentioned thing)?

Granted, I have zero power. I ask because I'm curious and just want to know.

It takes a long time to train medical professionals, and the current number is for the world 5-ish years ago (the training delay depends on the actual role, but that looks to me like the common one). If you want to have enough to cope with the extra demand from COVID, it will just take a long time.
