Most jobs will give you a performance review and a raise every year to account for inflation and any increased duties you’ve taken on. We increase minimum wage by massive amounts after far too many years which causes all sorts of economic concerns, business complaints, and just a bunch of arguments everywhere. Shouldn’t they just increase minimum wage 3.5% or whatever, every single year?
It depends on the goal. Are you trying to ensure a sustainable working class that can afford to support themselves and earn the wages of decent living? Or are you trying to create an exploitable poverty class that can be sapped for profit by oligarchs without admitting it?

I believe the first two chapters of that book may answer that question.
