This article made some really good points about the politics of the upper middle class (who I belong to). The author glosses over certain things like the real fear of not being able to afford to live in a low crime area (and yes, crime rates are correlated with demographics, and no, that doesn't make that fear illegitimate), but this is not central to the article.

I think the article has direct relevance to HN, where many people would like to protect the high wages of the tech industry, by opposing H-1B visas, offshoring (not such a big issue now) and campaigns to teach tech more broadly. People often conveniently forget or ignore market logic, which states that for the greater good, people should be given every opportunity to move into higher wage jobs, even though this will lower the wages of people in those jobs. These people often seek refuge in the thoroughly refuted logic of the far left, which states that even very well paid workers are still being "exploited" and that competition between workers of any kind is bad, and instead we should somehow seek to re-arrange the economy so everyone has access to the bountiful "surplus" that is somehow out of our reach. In contrast, the author rightly puts people on a spectrum of wealth, and points out that people far enough along this spectrum need to being arguing that they should have less not more.
