Well, my point was that you can go to where the action 'is'.
Defense/aerospace industry in the 60's, micro-processors in the 80's, database/ERP software in the 90's, and so on.
Also there is the insurance industry and the financial industry. You know about actuaries but have you thought about the world of financial derivatives ?
So the math person is either someone who wants the action or is not.
But consider Silicon Valley. Junior college drop-outs with ties to rich families get venture capital funding, become technology icons, and then run over to Stanford and hire all the professors. (And then no-one can understand the help files !).
