Race and low income are inextricably linked because of racist past policies, which fund schools vastly differently based on property values, which provides very different access to education, which provides very different access to opportunities in the future.
This particular commenter? I think they were 14 and just really stupid (edit: according to the Cupertino mayor, who was asked about a similar comment at 45:45 here [1]). So maybe not racist. But having spent enough time talking to adults who also talk like this, if you talk long enough the racist undertones become overtones. It's baked into our society, so though it's completely unacceptable to reveal these racist attitudes, the classist attitudes are slightly more acceptable.
It's definitely a dogwhistle to others, even if this particular commenter was not intentionally dogwhistling.
