my understanding is that Amazon does do something that others don't - that is to bring extremely advanced tracking and analytics to employee performance and activity. This is of course imported as a philosophy from its side as a technology company.
I'm sure smaller warehouses / companies would like to do what Amazon does but cannot because they do not have the size and expertise to do it.
The bad part then comes that in the past warehouse work has not been algorithmically optimized as it can be now. Imagine monitoring a machine very closely, pushing it ever closer to peak performance, as you push it parts start to wear out quicker but that is ok because your monitoring catches this wearing out of parts as it happens and replaces them as needed - no one cares after all if the parts are worn out quicker, what one cares if the wearing out of parts damages the performance of the machine and due to your much better monitoring of this machine the wearing out of parts never damages the machine.
Now take a step back and imagine the parts are human beings and the machine is Amazon.
