Hi there, sorry for the late response.
Ok, so first of all, the wage gap is totally a myth. You’ve probably heard that before, but it’s true. It is literally against the law (has been since the 60s) to pay someone less for the same job because of gender. Also, if companies COULD pay women less and get away with it, why the hell hire men at all? If they hired women, then they wouldn’t have to pay employees as much! But because the wage gap does not exist, we do not see an influx of women being hired rather then men.
The perceived wage gap is due to the choices of women, we are simply not as confrontational as men in terms of trying to ask for raises/bonuses. We also do not usually work as many hours. Here are some good videos/articles on this subject:
As for your second point, I can see why you think this may be considered oppression, however, I have a different view on the subject. After all, the legging rule was abolished, was it not? That means the school agreed with you and had tis rule changed. You see, dress code rules are usually buried deep within the district’s policies. It can take a long time and a lot of fighting to get them changed. The fact that it was changed at all means the staff of your school really cared!
As for the dances, while I agree that the chaperones should have done something, but I would offer a counterpoint. Is this really oppression? I understand that grinding is disgusting if done without consent, but I would say the best choice of action in the situation was to simply refuse to dance. If it was making several other girls uncomfortable, they had the rights to leave/stop dancing whenever they pleased. (That is my understanding of the situation)
Also, if the boys were allowed to do it, that means the girls were likely able to as well. The chaperones likely didn’t do anything because they really didn’t want to have to bother trying to herd the boys. Still a problem, but not oppression in my opinion. This is a very small problem.
Thank you for your time!
