Looked up some of them, and a good number are people who've been working there since the 90s. I know that if I had the same job for 22 years, I'd expect to at LEAST be making 200k...
If you do skilled labor, where you are constantly improving your skillset and becoming more productive or valuable (e.g. programming, law, custom carpentry, custom welding, nurse etc,), there is an argument for making a little to a lot more money after 22 years, but for all jobs where a novice and an experienced employee add approximately the same value there is no case for raising salary except to account for inflation.
