That's why we should give a fuck on their behalf. In a techno-capital society, it's too much to expect normal people to have to know the technical details of all of these things.
I don't know anything about water treatment or nuclear power, but I still expect the people working in those industries to be held to extremely high standards of competence, virtue and accountability.
We should have the same standards. We don't, so instead we need to demand regulations for these monsters.
