That seems more like a values thing than a process thing. I doubt that this process would produce terrible work conditions if Amazon actually cared about their employees well-being.
Capitalism is a game of extracting as much labour surplus value as possible. By definition an article praising Bezos' success must have employees not realising anywhere near their value add.
Bezos does not do the actual work, he facilitates the labour of others. And if he can do that and underpay them more than someone else would then we have a winner.
Implying that skillfully faciliating and organizing other's labour isn't work? Well, early on, soviet government and their 1918 predeccessors thought the same. They ended up with a lot of 'liberated' workers and farmers, and no managers and business owners.
Strangely, they had to restore capitalist system and then to invite foreign specialists and managers to make the industry even a little bit operational. Turns out, there isn't much you can do with dumb labour alone.
It is work but workers are not in a position to bargain for their value added. Bezos keeps it.
We should tax land not income and stop forcing people to under-sell their labour.
Spare me the "Russia" extreme example. This isn't quantitative, we can dislike that extreme and also the extreme celebrated by the USA which fails so many.
Bezos does not do the actual work, he facilitates the labour of others. And if he can do that and underpay them more than someone else would then we have a winner.
This is the system.
