Why yes, dialectical materialism does play into this. Very good.
When people work over a period of time, they expect higher pay, better benefits or even promotions. A way to offset this is to have seasons of firing and hiring.
Mind you, I’m not talking about small to medium size businesses, mostly large businesses with predatory HR.
You also have to remember that some hires are symbolic, in that some people were just hired to keep the employee away from the competition. I’ve met people who sat on their ass and did nothing for of all companies Apple (in that case, it was sales and marketing).
And again, it all stems from dialectical materialism, because junkie needs that line go up, get dopamine mmmmmm so good.
I.e degeneracy.
Remember; ideology and materialism cannot share priority in the human brain - so sayeth Engels and Marx, which means things like “an honest wage”, “free market principles”, etc, all go out the window, cus junkie needs it’s fix.
