I'm not saying that they shouldn't get paid more, and I'm also not saying that people in tech should get paid less.

But tying it to only salary doesn't create a balanced system.

There are occupations that are understaffed and have a need for foreign skilled workers that simply can not practically match what a FAANG engineer gets paid.

The caps on the available residency spots might have something to do with this as well.

"should be paid more" doesn't mean anything in the US or any society based in capitalism. With capitalism it's mostly supply, demand, leverage, and a few others. Compensation isn't connected to moral obligation.

And specifically FAANG engineer's price is established in a free market where as nurses and doctors are protected by licensure which drives their price above the natural market rate.

Therefore their wages should probably be lower.
