Something like Amazon is a partnership between the capital class and, to zeroth-order, everybody else, to screw over a small slice of the proletariat (their own employees and retail / warehouse workers) and the bourgeoisie (brick-and-mortar store owners).

It sucks when the capitalist Eye of Sauron focuses on however you make your living as a thing-to-make-more-efficient but when it lands on how someone else makes their living shit gets cheaper.
