just because a job -can- be done by one person does not mean that it -should- be.
this is a common failure mode for conservative-owned small business, btw - they habitually understaff their businesses to try to 'save costs' and go into a death spiral of poor service leading to poorer sales as a result.
and yes, I am specifically calling out conservative-owned small business here - the "used car dealer" class - as being the most likely to publicly state these kinds of systems-illiterate ideals* in public.
this illiteracy, and the class-based bias that
@nprofile1q... calls out in the post I'm quoting, tend to go hand-in-hand; they both derive, I suspect, from an underlying "self-reliance" meme, which in turn comes from a whole-ass bunch of early childhood development stuff** that is its own separate-ass rant.
anyway. the ideal in-use time of a resource is -not- 100%, and anyone who thinks otherwise should not be trusted to run anything other than their mouth.
* anyone competent in systems thinking immediately understands the concept of "separation of duties" allowing far greater efficiency and, in turn, cost savings; even elementary school children can, with coaching, be taught to figure this out.
** you know, I wanted to be a parent once upon a time? and researching early childhood development - because it's me, and if I was going to do a job I'd want to do it right, not fuck up monumentally in the way my parents did - convinced me that I was not someone who ought to be one.
