I think it was covered during a discussion about immigrants that are easily rejected - because they're immigrants.

The points was that it added another layer of issues for immigrants because they didn't understand the neighbourhood they "should be living in" with their revenue.

Why is this not the “shit people do shit things” category? This happens even without being immigrants. Large part of my family lives in a way poorer neighborhood than what we can afford, because we don’t care to move. People who have problem with this had other problems even before we got richer. There is exactly zero difference. The exact same people are snark as before, just for something else now. They were and would be snark even without this.

This seems to me a very bad attempt to hide xenophobia.
