I've worked for UPS delivery before, a long time ago, though only briefly. I liked the physicality of it. I can't speak to an Amazon fulfillment center, but I will say this: stress isn't only about physical demands. I think many people would prefer pure physical exertion (within limits) to long-term stress about job security. I think medical professionals can back this up.

One more thing. Often people's argument around these issues seems to end with: "it's better than no job at all". We can frame the issues in more constructive ways, don't you think? We should aim to find ways to adjust the system to better achieve the goals we want: innovative technology, fast delivery, fair pay, good benefits, subject to the complexities of the world.
