It sounds like you are describing capitalism.
I mean, if you’re at a place that uses staff aug and managing a project it’s just something you have to watch out from your vendors as table stakes. Whenever a new vendor was hired my fellow low level managers would be making bets on how long before they switched out their best guys with some fresh out of college junior that they’d give a fancy title to.
If you fail to take into account that you get into a broken world view of false equivalences.
