If we're comparing years of life, isn't one 16 year old worth 60-70 85 year olds in nursing homes? Maybe more because one year in the life of an 84 year old who's already experienced a full life is worth a lot less than a 16 year old going on 17. Societally wise, it's much worse to sacrifice a young person for an 80 year old who's essentially a burden on the rest.
This comparison of the value of a life is morbid, but we've been making decisions like this anyway, even if the media has refused to speak of it openly.
And of course this assumes that all these lockdowns, school closings, etc. made any difference. Again, we can debate that and both sides have data to make their case.
So yeah, maybe one or two suicides and the massive increase of unknown mental health issues weren't a good tradeoff for the unknown number of mostly elderly whose lives were extended a year or two.
