Your quote isn't from the article but a link in a post by kyoob (currently below this) that you aren't even replying to (were you so eager to beat hn's post throttling you put this on the main thread?). Kyoob's post already acknowledges this is also a poverty issue so your complaint seems a bit off the topic at hand.

It doesn’t sound like complaining. I think it could be a good faith point (and not someone just trying to find a way to downplay modern racism), although kyoob acknowledged it.

Obvious confounding factors should also be controlled for (or at least controlled in a side note).
