Seems like moist peope agree that age gap is part/root/primary cause of the shidduch crisis. Also seems like most people agree that close in age marriages will help at least in part. They may be other ideas that can help as well. Is there any reason NOT to continue to strongly encourge more close in age marraiges as that does seem to be taking hold.
Of course not to mitigate the other ideas being presented. I would just challenge those presenters to do something about their idea other than clog up cyberspace. Blogging is cheap. Let see some effective action. Put your money time and energy where your keystrokes are.
