Maybe the higher level learning is Bais Yakovs can be a bit much for the average student but I garauntee you, the smarter and more gifted girls would not survive in an understimulating environment. Gone are the days where a girl is born and bred in the kitchen. Like it or not, we live in an open world. We don’t want them to go elsewhere.
And many of these gifted girls are future “influencers” for Jewish women. Trust me, they’d be gone if Bais Yakov’s were only teaching how to sew and bake. Besides, Hashem runs the world, not goyim. If there is a differnt trend, universally, that women’s lives today are differnet – it is obviously part of Hashem’s plan.
