You are talking about niche positions. They aren't paying their front-end or developers 200k+.
I do know a number of bank developers making 300k+. They work on the boring, unsexy backend stuff that makes the bank run. Each of them provides the equivalent value of about 100 front-end developers.
Hmm ok. Because I know first hand that senior developers can get 220-300k easy. These aren't even owners or super niche. Just ~10yoe, and working on jira tickets nothinig wild.
