If anything, putting a specific price on the girls, will mean, that the girls parents, will want to have their daughters married before they turn 22, so they won’t have to worry about how to pay $4,000.00.
You will have more girls who will want to marry so before they hit the 22 year old threshold.
hurry, we have to get Chanie married before she hits 22 years old,otherwise, we have to pay 4 grand.
Everyone’s already trying to marry off their daughters at 19-20, nothing will change.
or the other scenario, shadchans not making shidduchs for girls under 22 so they can make money, once the girls hit the 22 years mark so they can earn more.
As the saying goes, “one in the hand is worth two in the bush”.
Besides, why would a shadchan wait for a specific girl to turn 22 instead of redting one who is already 22?
