What other points?
You missed what I responded: in the yeshiva community, all girls (well, most), even those who want to marry working boys, want to marry young. I think that’s a proper value, so if you want to change it by reducing the number of boys learning thereby allowing secular values to seep in to our community even more than it already has so that girls don’t mind if they don’t get married, I’ll have to disagree with you.
Also, if there were enough learning boys, the girls wouldn’t need to wait, so you are sort of being poseiach al shnei s’ifim.
