On a more serious note, I know a few companies who do treat their tech people like disposable inventory, on par with the lower-prestige roles, and it works out just fine for them. They don't get highly motivated world-class talent, but they don't need that sort of talent; just someone to take care of their relatively modest IT/dev needs. It's not very efficient across a lot of metrics, but low salaries probably compensate for that.
This seems to be a trend across all sorts of industries, less and less jobs that pay well, less employees that get coddled and treated well, commoditize the hell out of every last role etc. – just because it's not a big thing in much of tech yet probably doesn't mean it's an impossibility.
I think that day is closer than many imagine. If I take out well paying / no physical labor part I am as a Jira slave and daily standup chump are lot closer to warehouse worker than silicon valley type pampered engineer.
