I'll hunt those textbooks and try to find it, but "domain expert in finance" sounds cryptic.
What's the actual job title for the $400+/h job?
Oh, I once got an invite by McKinsey, but I declined the job offer. I believed that they won't support me learning more skills and that I can earn more as Software-Engineer. I don't know I was wrong now.
A quant is a Sofware-Engineer who knows a lot about "Finance". http://quantstart.com/articles/Self-Study-Plan-for-Becoming-...
I first heard it here on HN that one can earn $400+/h with a legal job!
And I'm deeply deeply impressed by that. I thought that only the dark-side (botnets/silkroad) allows one to reach or even top that amount.
