I'm not exactly sure what those photos have to do with anything, but what you say is true: there are situations where people stay in upsetting situations because there are no better alternatives. However, they key point is that they will still be upset. It's the "upset-ness" of these workers that I am trying to gauge. I say this because when a people are not upset, it is paternalistic and imperialist of another group to come in and say, "no, you're doing it wrong. You don't know it but you're unhappy. Here, do it the way I prefer instead." I don't mean to insinuate that nobody is upset. Just that it's important to keep it in mind, and to remember to ask.
