I disagree with this. It's more like "Doctor at the Mayo Clinic" or Johns Hopkins.

I live in a capital city of 60,000. Unemployment 4.5%, median household $79,000. Here, you're not seeing >$150K in IT unless you're a Director, or more likely a VP level employee.

Conversely, I drive by multiple homes that are being built or were recently built by physicians living in the area that are in the $2M range (our median home price in the area is just under $530K.

You can't say "the subset of one thing compared to the spectrum of another", because testers, tech writers (the "median IT professional") are not generally clearing high six digits even at FAANG (well, Netflix maybe, which is an outlier of an outlier).
