Here's my view - be quiet until you've read enough to know what you are talking about.
Paul Wolfowitz did not hire his girlfriend. He worked with the ethics committee to move her out of his chain of command, and actually moved her to a job outside the World Bank. Her raise was in part overdue and in part an apology due to being moved into a dead-end job.
The real lesson here is to not trust international desk-jockeys when it's going to be your job to clean out the corrupt desk-jockeys, or trust a Bush to stand behind you.
Thank you for the summation. I'll stand by what I said, though. Whether in business or government, having one's love interest in the mix is seldom a good idea. Not only can it be uncomfortable, it always seems to give ammo to your competitors and enemies.
