Precisely! And I worry that this is going to be how it is dealt with from now on. No investment in NHS training, staffing, infrastructure and so on. But "discouraging" mixing, threatening lockdowns, testing and isolating (sorry, "protecting"), making everyone wear masks and work from home for x months every year....
My feeling is that covid will become one of those respiratory bugs that kills some, and affects others less badly in the short or longer terms. As we each get it a few times over childhood and young adulthood we'll get more and more immune to its worst effects generally. So I would expect in the future that covid kills some people that flu or RSV or whatever would currently kill, or maybe a few more on top of that, and others have acute or ongoing needs as a result (hospitalisation, long covid etc). So surely we should invest now to allow for that forecast additional need (well, maybe we should have invested 2 years ago, but hey...). So staff can take leave, be off ill, be off to care for dependents or whatever, without the whole system falling apart. And pressure is taken off local services for eg long covid diagnosis and treatment... and also possibly covering other post viral illnesses that aren't well catered for at the moment.
Even if it ends up going "back to normal" in the next few years, having the capacity NOT to have the annual "aaaaargh, the NHS is overstretched" media round has to be a good thing, surely?!
