Not every person who has to have to job by “law” is essential
Except yeah, they are essential because the law needs to be followed.
If you want to change the law, then sure- those people are no longer essential. But that isn't reality, that's a hypothetical. Here in reality, the law requires people to be employed in order to have the law be followed(FOIA fulfillment, for example).
I listed multiple examples of people who were fired and rehired. They arent essential in the concept that if the jobs don't exist then yes life will continue, but they are essential in the concept that society doesn't want to lead poision our children, or unknowingly expose people to high levels or radiation, or for a nuke to not work properly.
Those are all extremely important jobs(essential). And they were rehired because the dummies that mass fired them in the first place realized the error.
'I track and reduce lead poisoning in children.'
YOU AREN'T ESSENTIAL!
'I help keep people from being exposed to high levels of radiation.'
YOU AREN'T ESSENTIAL!
'I help ensure the safety of our nukes.'
YOU AREN'T ESSENTIAL!
Step back and look at what you are arguing right now.
Reality is that mass firings led to a bunch of rehiring because they didnt bother to figure out what jobs are and aren't necessary before firing people. I constantly hear about how the Fed Gvt needs to be run like a business, yet no successful business would ever operate like that.
Mass cuts are dumb. Taking time to assess and reduce where possible is smart.
