Children are less likely to have adverse symptoms and pass the infection on than adults. But at the same time we simply cannot put literally millions of kids in a big infection-spreading paradise that is the nation's school system and not have a fair chunk of pupils get infected and spread it to their families and god knows whoever else, too.
Finally a justificiation for smaller class sizes that have been needed in schools for decades now.
I would have split students and had them go to class 2 or three days a week. So for example in an elementary school with 5 grades. I would have had grades 1 and 5 go to school on like monday and Thursday, then have 2 and 4 go Tuesday and Wednsday and have 3rd grade go friday and saturday. Or some sort of variation to split the students up and at least get them with some in-person school so that they dont fall behind as much, if at all.
t is everyone's responsibility to protect wider society, including the elderly. It's part of what civic society is. Old people have rights to do things with their lives just like you do, and it's not okay to imprison grandma in her home for a year just so you can live an inconvenience-free life. Old people need to go out and exercise and shop, too. Lots of old people need carers, and their carers have families and lives and can't be expected to lock themselves away either. Lots of old people live with their children and families, who can't go into total isolation. These solutions you dream of do not exist in the real world.
But someone who know's they are at more risks can take extra precautions that the rest of the population doesn't have too. At risk people already live different lives under normal circumstances, in which they are more careful with where, who, and how the interact. So extending that same idea to people who feel like they are at risk can take more precautions. Simple.
Why should had office of tech support 20-somethings have to stop work entirely because a segment of society they do not interact with ,or even see on a regular basis? I don't think it would be unreasonable to ask the younger people to clean up, wear gloves, and masks, if and when they go visit their elders. Meanwhile the whole world didn't have to stop.
Of course this is fantasy because it obviously didn't happen, and anything we come up with is hindsight based off current experiences. Hindsight is 20/20 after all.
I think if anything, the fantasy of saying "We could have prevent ALL C-19 deaths" is just a dream. This was always going to kill people, but car accidents also kill people and we don't shut the roads down to stop road fatalities. Hell the common cold kills people.
You also have to consider this:
How many people are dying BECAUSE of Covid, versus people who are dying who also HAPPEN to have Covid. Because there is a difference. Someone with heart failure, lung cancer, or whatever is already dying of those issues, is it then fair to say that their death was because of Covid when without it they were going to pass in a short while anyway. Like think about all the nursing home deaths. People in nursing homes are dying and need constant care to stretch that life out as long and as comfortably as possible. Nobody goes into a nursing home, and then gets better and gets to go home. So Covid ravaged those places basically acting as the tipping point for people who were already walking on the cliff.
Which isn't a justification of anything, but it does make the numbers a bit misleading IMO. Run the numbers and see what % of perfectly normal healthy people got Covid and then passed solely because of it. And I would imagine the number is going to be incredibly low.
