Because we live in this fantasy land of the [dead] 'American Dream', where if you work hard, absolutely bust your ass and kill yourself for 70 years, you'll get to be Jeff Bezos too. If you're complaining about your job, just get a new one, or pull your boot straps up and accept it, it's that easy. We're constantly told to suck it up and accept it. We're constantly told that these businesses are job creators and should be praised for it and when we criticize them, it's not their fault, it's the workers. We don't criticize because we can lose our job and it's extremely easy to get into homelessness now, or default on the enormous amounts of credit everyone has. The propaganda and indoctrination start from birth and is built into society. The atmosphere changed from workers having control, to businesses having full control. Businesses can't exist without workers, so workers should have control. Anyone who says workers shouldn't have control is a shareholder or business owner.
To change things will take a lot of work, and possibly a major fast economic decline. People have ignored the economic decline of the working class since the late 60's, early 70's. Mainstream media and newspapers work to suppress any workers movements and tell you how great everything is (Noam Chomsky's Manufacturing Consent goes over how this works).
