While I agree with you that Bais Yaakov’s have lost the vision somewhat, firstly, the doros changed, and with that the vision has to change as well somewhat. Every school has daas torah that they consult and try their best.
Yes, we should’ve been taught more on how to manage the home. However, many feel that this is something we’ll pick up anyway and is sort of a waste to teach.
Bottom line is, if you want your daughters to learn less, send them to a chassidish school, where the emphasis is definitely diff than the Bais Yaakov’s.
