Unless Al Zone convinces some of the 24b’s to marry some of the 26g’s and then the crisis just lasts forever.
No, because if 26 year old girls are still in the shidduch pool, and there are enough boys for them, there is no crisis.
In other words, yes, that will leave out some of the younger ones, but they can still get married later.
Of course, in a world in which there were no population growth, ch”v, NASI wouldn’t need to convince anyone to marry older girls, and Rabbi Pinchos Lipschutz would have to find other ads to fill the pages of his publication.
