I think the point is not that people wouldn't care at all, but that most wouldn't jump straight to the assumption that this is entirely due to public schools doing something horrible to the children, but rather that this reflects a broader societal problem with mental illness and mental healthcare[1]. By contrast, there are plenty of people whose brains consist mostly of a soup of simplistic media tropes, who are primed to think of "tech company hiring low-wage workers" as combining the worst of Dickens and Black Mirror and thus jump uncritically on flawed data as evidence of horrific conditions. I think previous reports of Amazon's warehouse policies are concerning, but I don't see the utility in being dishonest or sloppy with the facts of the situation. [1] I'm aware that many do think of (some) public schools as hellholes, but they'd be correct not to assume that the problems describe all or mostly originate with the school's actions.
