The private sector attempts to control its own. SCIP, the Society of Competitor Intelligence Professionals, has a code of ethics that wouldn't approve of this article. How many SCIP members adhere to that code is a separate question, one I'd rather not know the real answer to. Similarly, hiring managers and recruiters will sometimes interview for phantom job descriptions, the real goal being eliciting competitor information.
Patriotism, religion, legalism, altruistic idealism... there's no shortage of things we can cling to when doing the right thing is difficult. But without accountability & enforcement, unrestrained competition makes unethical behavior almost appear to be a necessity. We really must do better, but we are now so far removed from the collective consequences of our individual misbehavior, the road to ruin might be unavoidable.
