On first glance, this person seems to be arguing from some kind of moral high ground.
However....
Anyone who refers to places as "3rd world shitholes" loses legitimacy in my eyes. It is my experience that people seem to be happier in many less-developed nations than they do in the USA, and they often have a fierce sense of patriotism. It's completely self-centered to think that people remain in, say, Cambodia or Bolivia only because they can't escape to a "better" place.
I imagine that this comment was made in the vicinity of a North Face fleece and multiple pairs of Ugg boots...maybe an expensive -- but unopened -- cultural anthropology textbook too.
