It's a little dramatic for my taste, Occam's Razor probably applies, but there might just be a grain of truth to it... at least in the darwinian sense where incompetent time management just so happens to somehow beat workers into submission better than competent time management happens to retain them. The incompetent managers win out over time and a dominant pattern emerges.
Another is using immigrants or poor people trying to establish themselves as managers in name, but in reality they are there to fill in for the lower paid shift workers who are constantly quitting or unreliable because they are paying the lowest wages.
The “managers” put up with this to earn a steady salary paycheck, but per hour worked, it frequently comes out to less than minimum wage.
Obama admin increasing minimum salaries to $48k from $33k had the small business owners I know frothing at the mouth.
