AZ, this will by no means increase the number of boys!!!! The only thing thats rising is the Shadchanim’s pay. The guys who are red to way younger girls, will still be marrying them, with Nasi’s blessing or without. There will still be the same number of girls left without guys, at the end of the day. Its at best a band-aid for a hemmorhage.
I havent the faintest idea what the solution is, but it sure aint this. It’s like chocolate, it temporarily makes people feel good, depositing their money for what will be in most cases false hope.
