A screwed hiring system is something most companies appear to be able to afford, given how many have one. When that same experience is flipped around to the employee, they can't afford it and it's a disaster. Few employees want zero job security and an expectation to be wading through the job hire swamp every couple of years.
You're not describing an employee, you're describing a consultant. Not everyone wants to be a consultant, particularly since most people don't get any training in it before they have responsibilities. If proper entrepreneurship was a subject at school, then maybe people would be willing to be their own business, but that's not what the system creates (or wants).
Fair, I can see why this might bother people. I don't think job security is a thing (career security perhaps), but I can get why its absence would be disturbing.

The high level of turnover in this industry indicates that people at least tolerate it. The only people I know who make it 24 months in a role are chained by stock options.
