I don't have much of a problem with the argument that worker conditions are bad and should be improved. It's a valid subjective call. But I'm more skeptical of this argument:
> Although it may seem like the company is saving money — because you don’t have to provide temporary workers with medical coverage or paid vacation time — the revolving door of new hires encourages low quality work, inconsistent productivity and wastes useful resources on training.
I find it very hard to believe that an Amazon contract worker, based on his experience, is more qualified than Amazon management to judge whether this practice is financially good for Amazon.
