An academic discovers what most observers already know:
Although this may be considered an unflattering characterization, and it cannot at present be considered a proven fact, we have found no evidence to contradict the basic general principle that men will do whatever is required in order to obtain sex, and perhaps not a great deal more. (One of us characterized this in a previous work as, “If women would stop sleeping with jerks, men would stop being jerks.”) If in order to obtain sex men must become pillars of the community, or lie, or amass riches by fair means or foul, or be romantic or funny, then many men will do precisely that. This puts the current sexual free-for-all on today’s college campuses in a somewhat less appealing light than it may at first seem. Giving young men easy access to abundant sexual satisfaction deprives society of one of its ways to motivate them to contribute valuable achievements to the culture.
Add that those of us who tend naturally to the romantic, funny, loyal and enterprising tend to get the sucker's payoff - get kicked in the teeth for the trouble.
I'm not sure who said this first, but men will behave as badly as the women around them will tolerate. Women wielded far more power when they were "inferior", before they were duped into settling for equality.
