None of that makes sense to me. Sure it sucks to be in such a shitty place that you just have to take whatever pays, but that's the reality for a lot of people

None of that makes sense to me. Sure it sucks to be in such a shitty place that you just have to take whatever pays, but that's the reality for a lot of people and I don't see anyone being all morally outraged at people who hire construction workers or whatever. It's like you're saying that having sex is so terribly bad that it's better to let people starve instead, but that's a bizarre idea considering the fact that sex actually feels really good. What would you do in the car washing example? Drive back to your city and pay $10 because paying someone who's willing to do it for $1 is exploitative? Surely the people doing it for $1 would rather do it for $1 than not do it for $0.
