Both typically impose net costs on the country that has them, although in both cases there are possible exceptions. If I am a thief, I benefit by my theft, but bear costs due to other people s theft, since I may be a victim directly or have to pay in higher costs. So if I am a marginal thief, doing only a tiny bit better by theft than by an alternative profession, abolishing all theft probably benefits me. If I am a very good thief, then the loss from my being unable to steal probably isn t compensated from the gain through no longer being a victim. Suppose you have been attending a coed college, with roughly equal numbers of men and women.
Woman have their pick of men.
Men modify their behavior in ways that make women more willing to date them. Women are less willing to modify their behavior in ways that make men more willing to date them. In both cases, assume each college is located at least an hour or two away from any other college.
