The upper middle class is ruining America

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.
Here's how many people who support immigration but are skeptical about the tech visas see the argument:
Claim: "there is a critical shortage of tech workers, therefore, we must change our immigration system to favor tech immigrants over other kinds of immigrants".
The response: "although immigration is generally beneficial, the evidence does not support claims of a specific tech worker shortage. Therefore, we should pursue a more general policy of immigration, and allow immigrants to respond to market signals when they choose a profession, just as free citizens and residents do".
You are right that there is no reason to single out tech. However my claim is that this is because other professions have been successful in implementing the harmful protectionism I and the article were referring to. There is not a critical shortage of tech workers in particular, but high wages indicate a shortage in general. There are also valid reasons to focus on tech, e.g. tech skills are more transferable internationally than, for example, law.
I've long been fascinated by the negative way unions are described in the US, while the unions that protect doctors and lawyers from competition aren't even described as such.
Again, the article is a waste of time.
