Federal legal jobs are sweet gigs. You don't get rich, but you typically don't have to work very hard (unless you're in a high-crime-area US Attorney's Office like D.C. or New York or Miami) and you have great benefits. Plus if you do want to make money, a stint with the feds can be a good springboard to a big firm or in-house with a megacorporation. I have a friend who began his career as a lawyer for the FTC and then he jumped ship to do policy work at Intel and Amazon where he's a VP of some hoity toity thing or another.
But lawyers are generally insufferable twats, I agree.
