"Employees are paid salaries that allow the shareholders to extract as much profit as possible.
And innovation forces the gap wider between the needs of the shareholders at the top and the employees who are moving closer to the bottom.
This is not a bad or a good thing. It’s reality.
Corporations want to ultimately fire you, whether you like your job or not. Their entire purpose is to create and squeeze the efficiencies out of you until you drop dead or are no longer needed.
You can love your job so you don’t want to quit. But the company that hires you eventually will quit you.
Eventually they will squeeze every bit of profit out of you. Eventually you will join the class of workers who have become outdated. Eventually they will fire you."
