It may be a zero-sum game (no idea), but it's still a good idea to change what can be changed, instead of invoking some grand principle (I'm all for grand principles; it's just that the result of invoking them is either changing what can be changed or doing nothing constructive, usually the latter.)

Besides, it's not really good for women, per se, if the jerks are a bit less successful; it's equally good for everyone who isn't jerk-ish, which includes many men.
