The same politic groups, that would argue that teachers are the heroes of society that we can't live without, are now arguing that school must under no circumstance resume. We must indefinitely put off in-person schooling.
What? Is this the best we can do? Does this even measure up with scientific reality and risk calculation? Are teachers really that simultaneously important/unimportant? If the grocery baggers are working and handling the crisis well enough, so should teachers. It's clear that there's a class element to "essential worker." And this entire profession that seems to love the praise they generally receive from the left about how indispensable they are, are now suspiciously absent from the essential worker category.
You can only conclude that the social and mental development of children isn't essential.
If they cared enough, they'd use this crisis as an opportunity to start hiring younger teachers in droves to build up the workforce with relatively inexperienced teachers who aren't at much risk from the virus (at least compared to some 50-60yo teacher). But I suspect unions would stop at nothing to impede adaptive, efficient, and creative solutions.
