I was thinking more about the JAMA paper.
The authors carefully supported their assumptions about Years of Life Lost (YLL) from COVID-19 and their extrapolations based on children's loss of educational time's impact on life expectancy without intervention, resulting as I said in 84 days shorter lives, on average, using their figures.
The total, across the 24.2 million children was a total more than 3 times that of the YLL from COVID-19 total in their evaluation or the prevented YLL because of the closure.
But a couple of items confound their calculations:
1) Their examination of YLL from COVID was based on early months, before this autumnal wave that has blown away the highs of the Spring. Their calculations of deaths from COVID - both caused and prevented - are grossly out of whack. 88,241 deaths through the end of May, according to their figures. (Setting aside that they took the "through end of May" numbers before May was done being calculated, leaving them more than 21,000 shy of the real death total and the real YLL and a more real extrapolated YLL prevented!)
2) There is no mention of nor hint of awareness of the "long haulers," those with symptoms impinging on their lives long past the presence of the virus itself. One paper in Nature suggested that that percentage was certainly below 10% of those who had tested positive, though how much below they were as yet unsure.
The result is that they don't know the YLL for those folks, but if we assume it is only 1% who suffer from lifelong debilitating neurological or organ damage, that is still an additional 180,000 or so people losing some parts of their lives to COVID-19. How much? We don't know. Not even slightly...
3) Their estimate is that for every person who died in the US, the average number of years lost to COVID was 17. Seventeen years lost vs. 83 days lost.

We've kept more kids home, without totally shutting down the schools in most places. I am sure a bunch more kids will have had their lives shortened by lack of educational attainment caused by these days of missed school, but not nearly so many, while the saving of lives continues, to an extent, with the online schooling.
They might even be averaging 100 days shorter, versus the 17 years in those whose lives they are saving.
Ask them if they would make that trade.
