Also what number of orphans is acceptable? 30% of the US won't vaccinate. Delta has a mortality rate of 3+%(1) by the most charitable takes. Rough math would show that could add somewhere under 1 million orphans to the system.
Do we also ignore medical costs for those who get sick? What about the hospital resources those people take up?
Again, there's just so much more than "just the children"
1. I'm estimating 3% for Delta by taking the NHS estimate of 1.9% CFR for Alpha and the subsequent estimates that Delta had around double the risk of fatality.

EDIT: HN won't let me reply to the comment below me until the cool down period. They say my argument is not in good faith, which is an odd assertion to make. Their comment assumes a higher case count than reported, which while likely, is not an assumption I'm making because it's hard to discern whether there is also therefore uncounted mortality.
Indeed. Parents should also be vaccinated. It would be reasonable to delay school until that point. (This is an additional delay over those previously mentioned in parent comments in this thread.)
However, we should also expect that all parents will be exposed to the virus sooner or later, as we have been told from the earliest days of the pandemic, and thus we should limit further delay.
Yes, parents will get COVID from kids who go to school. Yes, unfortunately, there will be children orphaned as a result of that exposure. No, there won't be substantial numbers of net orphans -- certainly not such that crippling public education for years or even decades is the more humane response.
