The obvious methodology at work here is 'fire everyone then hopefully re-hire only what is blindingly obviously needed'. There are many, many problems with this approach in a business setting but even more from a governmental setting. The first, and what should be obvious to anyone with an ounce of empathy, is that these are real people who's lives are being toyed with. It isn't like you are trying out a new business…
It's about benefit to society per cost. If you can fire someone over here and hire someone over there in a role that brings more benefit to society, that's good. Eg. Fire the telephone sanitizer hire the addict rehabilitator.
