I'm speaking to cultural biases in the west, I'm not speaking from a personal perspective. Physical laborers are percieved as humans of lesser value, and that's why the bar or standard for what is mistreatment of them is much higher. We do the same with, for example, prisoners. They are humans of lesser value, so the standard for mistreatment is really high. We can force them to work, physically hurt them, starve them a bit, and the average person doesn't care. We have to do something really bad for people to start caring. That's why your office worker can take a 15-minute walk and nobody bats an eye. But the grocery store cashier wants to sit down, and millions of people lose their mind.
