We should never have closed schools, or at least reopened them ASAP. We should not have implemented the ludicrous "bubble" system and we should not have prevented kids doing fun and healthy things like sports clubs for a year.
We've been through this before; I refer you to what I said previously.
Unfortunately the measures which people such as yourself have supported and/or implemented have caused mental wellbeing to be at an all time low; while there should be more "support" the reality is that trying to fix a problem that should never have occurred is not always an easy process.
We should be doing more to identify the root cause of these issues and lockdowns etc have exacerbated these problems massively.
I don't see evidence that schools have "fewer resources" for example loads of laptop/chromebook devices have been provided to schools, and in general schools seem to have better resources these days than they did, but for a long period of time during the pandemic, schools had staff who were not allowed to do many of the activities that they were being paid to do, on the basis of "preventing the spread" of the virus. This resulted in all sorts of problems, for both mental & physical health as well as having an impact developmentally and academically. I remember in the Summer of 2020, when virus levels were very low, kids in my city had no opportunities provided by schools because the local council had instructed them all not to, and all schools had agreed to this.
It was absolute madness and yet people like you supported it; I knew it would have a terrible outcome but we all make mistakes, and I respect that, so it would be great if you could just admit you made a mistake in supporting these measures? If you did, I'd have a lot of respect for you for that.
