>What if I have a very specialized skill that doesn't fit nicely into your matrix?
Oooh, or what if there's a dragon[1], and I need to be paid extra money so I can spend it on dragon-slaying gear? If you really deserve extra money, the conversation goes like this:
"Why do you make more than me?" "Because my job is harder."
Fun fact: you're not that special. Wage secrecy is good for skilled negotiators and bad for everyone else; being a skilled negotiator does not, however, ethically or morally entitle you to make more than other people. It just allows you to get away with it, and it's trivially unfair.
Dunno, if person A goes to gets a PHD in distributed systems and spends 40 hours a week furthering their knowledge of computing topics, while person B spends 6 years after university uninstalling viruses from windows computers, and spends their time after work watching cartoons, it seems very plausible there would be a significant difference in their worth to a company due to a significant difference in skills, even if they are both hired on as "developers".
