Ok, fine, I will bite.
Now let's say the university alters their courses to be more attractive to women. But the jobs that engineers will not change. You may want to change them, but if they want them to actually achieve something useful, they really can't change. It's like asking painters to be more like actors, so actors can also enter the field of painters; this will not create more painters, since the skill of painting, remains the skill of painting.
"more societally meaningful" ?! And I don't get it either. My job does not get more societally meaningful; if I don't do my job (Software Engineer, Industrial Automation), you don't get any power to your home, don't drive a car, don't get air condition in the mall and many more things. Sure I am only a small cog in that bigger scheme of things, but without engineers modern society would not exist.
I would like more women in engineering; many of the colleagues I like to work with are women. And talking with them, the content of their work is not what is holding them back. In some cases it may be social or cultural and in other cases just "math is hard".
On that note, I demand more male nurses!
