There is one aspect of all of these theories that nobody has brought up yet as far as I can see.
The way the system is setup now, our daughters are being well educated in their yeshivas because its a good possibility that they will be the breadwinner of their own families.
The boys education, at least in the very frum community I live in is dismal to say the least.
The problem then becomes that my daughters have trouble dealing with the boys their own age (or younger) because they are so poorly educated.
My daughter dates boys close to her age and just comes home rolling her eyes…The younger boys, who have very little life exprerience, are so immature!
If we want our boys out in the dating world sooner, then they need to be prepared!They need to be educated better then they are now. Even if they are going to sit and learn forever, They have to know how to balance a checkbook or how to carry on a normal conversation complete with proper grammer.
The well educated girls should be able to respect their life partners and not feel educationally and worldly superior. That alone is a recipe for disaster.
Give the boys a little real life education and experience and then push them to date younger.
