Ph.D. in physics?
It ain't that simple.
It would be an injustice to myself, to society and to my colleagues to NOT work in the field that I've invested the last, oh, eight or so years training in. Not to mention all the time and money that's been invested in me by other agents.
I should at least be one of those dudes running around with a clip board and a pocket protector...
I'm not tryin' to pull the arrogance thing on ya; I'm just stating fact. And yeah, if 30's-style depression came upon us and there were literally no market whatsoever for my skills, sure I'd be racing you for the next available shovel.
