> that they act against their own best economic interests?
If you consider just your own "best economic interest", a lot of "jobs" like drug dealing, prostitution, fraud etc. are good choices. Morals, not wanting to go to jail, and a concern for your own physical security are non-economic factors that make these bad choices in most people's view. Blackhat hacking falls pretty much in the same category; selling exploits may perhaps be technically legal, but I wouldn't bet my paycheck that you couldn't be put behind bars for aiding and abetting in a criminal offense or similar.
