It might not be total shake-up of civilisation, but it's not a fine line between "everything gets back to normal" and "nothing is the same ever again". It's a terrible overlap with the worst of both worlds.
I, for one, hope that our medical professionals don't all burn out from the strain (though I know that many will, and a lot already have), but I also have less sympathy than I rightly feel I ought to when it comes to those who would continue but are being 'forced' out due to insufficiently pro-vax attitudes.
(Let's be straight here, if there's someone thinking they can care for people who doesn't care for themselves and everyone they come in contact with, then there's a problem. It might be insufficiently communicated reasons, failing to actually convince rational people. But I think there'll be a fair few 'woo woo'-believers who it is a pity we needed to plump up the numbers beforehand.)
There'll be a mess, and healthcare systems are famously close to the breaking point at the best of times. Aiming for 95% utilisation at the best of times already causes a "winter flu + icy slips and falls" crisis every year around this time of year because of false economies and self-defeating 'targets', over here. Not that ours is the worst healthcare setup, though it is somewhat degraded by all kinds of less than useful policies, both direct and indirect.
So how we get through to the other side, with currently inspired fresh young things having by then completed their medical training and forming the newest cohort of care... Idunno. It's not my department to sort it out, and while I'm cynical enough to expect spanners to be figuratively thrown in the works by all kinds of people I also have to be hopeful enough that the new-normal will end up being better than it could have been, that we will reach... if note the 'promised land', certainly a decent facsimile of it.
