That's not what they want though. What they really want, is to pay the best person they can get the absolute minimum they need to pay them.

They don't think about "what is the value of someone doing this job properly?"

They are counting on candidates not knowing their worth and exploiting that, and this guy is basically saying that

Not happy in my work environment here. I’m not quite to 135k but I’m over 100k. I’ve scrolled through looking at jobs and still skip jobs that pay 30k less.

I would love to be making 135k. And I would be very content. But A) baseline cost of living is different everywhere, B) Some people support big families on one salary, C) Some people have others that they care for with chronic health or developmental issues that are very costly, etc. So not everyone would necessarily be content at that salary. Plus, if you are making 135k and you CAN be making more, there is no reason not to be looking for opportunities to do so. There is no honor in making less than you are worth to someone else just because. Job hopping to get that raise is very much perfectly reasonable. And having more than you need means you can be generous and give to those who don't.

Even being unhappy I'm not switching jobs unless there's going to be a pay raise. No guarantee the new place won't be worse. Unless I somehow manage to land something that pays the same but lets me just fuck around all day.
