I understand the logical reasons parents send their girls to sem, but let’s talk real world over here. For many many people it’s simply unaffordable. And for those that can afford it, shidduchim factor in way more than they probably should in choosing the “right” seminary.
And seminary costs are significantly more than college. You can go to a local college and sleep at home, pay in-state tuition costs, and get a full 4 year degree for less than half of one year in seminary.
