At my first job in financial software, one of my coworkers was an MIT-grad aeronautical engineer with ~5 years experience in aerospace, ~6 months software. He took a pay cut (though not much of one - I think he went from about $90K -> $75K) to get into finance, because aeronautical engineering doesn't really pay you enough money to have a decent life in the Boston area. Within 2 years he'd jumped ship to a hedge fund and was making about double his aerospace salary.

And people wonder why we don't make things in the U.S. anymore...
