In times past, girls were taught humility from day one. Life back then in general taught humility, but an extra helping was heaped upon the girls. Why was this?
Partly it was because they would rather soon have inordinate power; power not commensurate with wisdom or effort to obtain it. Those who have worked diligently to develop their skills and the power these gave to them can appreciate their employment; as they were obtained through work and should not be frittered away frivolously. As a substitute for this earned perspective, humility can compensate partially. A humble girl/young woman is less likely to attempt to exploit her youth and beauty than an “empowered” one. Or so the thinking goes. And by reining in her exploitation, she does less damage to herself and society. In short– a humble girl may feel herself unworthy of exploiting her attributes.
The flip side of the humble coin is the situation as it exists today. Children, most especially girls, are marinated in self-esteem at school and at home. “You are awesome” they are told, with their actual ability to accomplish anything more or less irrelevant. Then the young girls become teenagers and realize how much power they do have. It is natural enough to exploit this power, and as being awesome creatures they clearly deserve to do so.
Mom and Dad (and often inexplicably Dad) contribute. Because she is an awesome creature in a so very tough world, she deserves more in order to attain her rightful position. And the list of goodies is nearly endless, fine clothes, fancy cars, “study abroad”, expensive universities., etc. It is more likely that girls receive these goodies than boys; as men of course are still expected to make their own way in the world. Consider friends and relatives that you know. Is this pattern followed with their children?
The result of all of this “good stuff” just being handed out to girls/young women for no apparent reason is that they come to believe that they are entitled to it. And then the fun begins.
