The thing that they forget is that is TSHTF, all their employees will be looking out for themselves and their families. And they will not allow their families to starve and be murdered while their employers are sitting fat dumb and happy.
The rich know this and undoubtedly have both provided for the employees’ families to incentivize the employees and have various failsafes in place in case people get out of line.
They’re generally not stupid people.
