I believe salary levels are the same for everybody regardless their profession. Which means whoever starts with 90$ as a beginner will end up with 300$ as a master.
BTW, bethlham, I also had master rocket scientist. A blond one.

For the highest salaries (well, I admit, I'm greedy ) - I have lobbyist and programmer

Level 1 105$
2 135$
3 174$
4 204$
5 240$
6 282$ - update


Engineer, Rocket Scientist
Level 1 90$
2 105$
3 129$
4 168$
I don't remember the rest, but at the end it was 300$.

Digital Photo Editor starts with 60$.

Level 2 75$
3 90$
4 114$

All of them work in the office.
