> The problem isn’t the wealthy people per se. The problem is industries like tech that generate highly paid upper middle class jobs that most people aren’t qualified for (and realistically will never be qualified for), as opposed to a larger number of middle class jobs that most people can be qualified for.

You talk as if that is a problem. If you are surrounded by rich customers you also get to charge more for your low skill job. The problem is that there isn't enough housing for both high skill and low skill workers.
