mental health issues exploded

Because people actually had time to realize how fucked things were, instead of being corralled into the office every day like cattle.

I mean, there may be some truth to that, but we cannot deny the damaging effects isolation had on people. Not to say that isolation was not extended exponentially by malicious actions and incompetence, but the isolation caused many of the mental health issues (which also means those who did what they were supposed to best suffered most, which really sucks).
