Women artists in museums

I was having issues as to why intro art history courses (it depends maybe also at what time period the class is discussing), never touched the issue of lack of women artists. I remember going to a panel last semester with profs on the panel from history and other subjects. But even they thought that it was important to talk about either the lack of women or the role of women even if it was not necessarily in the course book. When I talked to my art history mentor about it, the only prof that actually teaches feminism in art, why it isn't discussed in class. He mentioned the fact that there is a greater prevalence of women artists in this time period. And I do understand that there is a canon for art history, i still think that its very important to talk about it especially in an intro art history course.
     I started to look at the collection at SLAM, how great the differences were in number of women and male artists. There is such a huge disparity still within the numbers. But not only that some artists in the museum have more than 10 paintings or pieces at SLAM. With the image  from guerilla girls although that certain photo goes more for auctions/monetary value of art/the fact that art from women barely touch the price value of art works from males. I would take a big guess that for the most part the paintings from the males would have been much more expensive. The highest I have counted so far was from Max Beckner (german expressionism, which i didn't think would have been that popular here but hey why not) with about 23 paintings. I was wondering what if with that money they had bought female artists' artwork rather than having such a high amount of paintings from one individual.
    I'm not taking away that the male artists are not any good, but why are they far better distinguished and respected. I understand that idea might not be as heavily thought of compared to just the 1900s (an example being Steiglitz being unhappy with some of O'Keefe's works when she started to depart from flowers because it wasn't representing females anymore/essentialism). That thought still exists today, I don't think that any female artists any time soon would be breaking the most expensive painting auctioned like Francis Bacon's triptych for about 142 million.
   I'm not asking to be inclusive for the sake of bring more women artists into the space of museums, but I do not think that there would be such a lack of female artists in all styles of art. I thought that maybe the contemporary wing would have provided more since it contains work from post-modernism/closer to this time period. But it was about 61 male artists to 13 females, I don't get how there are only 13 females to 61 males especially within contemporary.
