I, like you, don't like it the way it is when it comes to remote IT job market, but it's very clear how this works. In country X average full stack developer charges Y dollars, recruiters know what average pay is so they will only offer pay within same range (or sometimes slightly more, like 5% more). Companies look for cheap labor and will not pay more than they really have to.

Where I live now the top pay is around $100k per year (fully remote full stack, but similarly dev/ops). Extremely rarely (maybe once in a year) I see an advert paying $200k and since everyone wants to earn this much the competition is enormous. This also applies to FAANG who don't pay more than average market rate.

I don't know if my observation is close to reality but from what I see better paid positions are usually not going through public job boards but through word of mouth and through networks.
