fwiw, my son is NOT a trader or salesperson, but for point of reference...he works at Goldman, in systems. An elite (his word) group of 20 CS mostly young in their 20's, their work involves the technology for the actual trades (I'm a lay person here so cut me a little slack

.) I believe he said $10 billion a day goes through his group.
Anyway, for Caliguy...he's 2 1/2 yrs out of college. Starting salary in '05 was 60 K bonus 10K. Don't let that sway you. His first FULL year out (after initial Aug to Dec stint) he was over 100K. His second and most recent year-end raise was 42% increase in base salary, and his bonus equalled his salary. So age 25 making $200K+, I can only imagine the future. And that's easily enough to live in Manhattan and save tons of money(tens of thousands), esp when it arrives as a bonus in a chunk. And I repeat he's not actual trader who apparently make a lot more (no interest in trading, CS major who loves technology but great mind for finance which is helpful) so I agree with the higher numbers given here as being entirely possible, and probable.
