People often talk about how the poor in the US still live better than the poor in the third world, but the poor in third world countries are not excluded from renting relatively decent places because of bad credit, they don't give away their class by their bad teeth, they (mostly) do not have to sleep under bridges (unless they have serious mental issues), their mobility is not restricted by the need to have a car (which all the attendant on-going costs), and so on.
I could be dirt poor in a third world country and people will not avoid me like I am some sort of defective, repugnant, morally challenged person; I am still normal.
Thanks for the insightful comment.
Very good point. I have been living in a lower-middle class neighborhood in one of the world's poorest countries for around 3 years now, but I'm originally from the US. There are fewer inherent indications of wealth vs. poverty here, whereas in the US you can often tell at a single glance. Even if you literally strip away social indicators like clothing, I think I could gauge someone's economic status from their naked body (sadly), and if not that, then definitely from their dialect.
