That's very theoretical and not analogous because the difference is that sys admins have to do things quickly and under pressure, sometimes at ungodly hours. In contrast the banker has a more relaxing experience putting his signature on a document. It's stressful enough running root commands sometimes, and I can't imagine how horrible it would be to require a second person to be on-call/pair/double-check/etc. I would have long ago quit the profession, which would be impossible to do anything in. Also systems would take longer to fix, so organizations would be displeased. Vet your sys admins correctly before hiring, keep an eye on people's stress levels, which in 2016 America apparently doesn't matter to anyone anymore in IT, and don't piss off the sys admin.
