Training oneself to become a hacker and then working for the NSA is like graduating law school with an emphasis in environmental law and then working for BP.
Except you hackers are already sellouts. Hackers complain that the United States does bad things in order to ensure a smooth oil supply, but then they fly or drive to Las Vegas for DefCon. In the hacker's mind, they are not to blame for burning oil, companies like BP are to blame for selling them the oil. While at DefCon, hackers consume vast amounts of electricity and water -- in the middle of a barren desert. Even the cheapest Vegas hotels are more luxurious than "nice" hotels in the third world. Hackers enjoy all the benefits of a peaceful, prosperous society created by our government and corporations, while complaining about how those benefits are obtained.
