The narrative has been changing continually during the pandemic, which is to be expected since we've gone from not understanding what it is and realizing that we were completely unprepared, to lulls where we thought we were getting over it, to spikes where we were largely willing to use what we learned earlier on, to the current spike where people are figuring out that this may be with us for the long run.
As for holding people accountable, where would we even begin? I saw politicians closing beds and physically demolishing hospitals 30 years ago. Politicians of varying stripes did little to rebuild the system after that. While there was a push to hire more people at the start of the pandemic (both in health care and education), the interest seems to have dwindled off since no one wants to deal with the long term costs. Even if they were willing to live with the costs, few sensible people are willing to take on those roles because the involve continual sacrifice. There is also no guarantee that months or years of training will be rewarded with a career since the demand is likely to be short-term. There are so many people who can be blamed, so many people who should be blamed, but it won't address the problem since the decisions were either made in the distant past or are a consequence of inaction rather than of action.
