The big prize is the necessary structural changes. Hopefully one day that will happen.
That is what BPT, RC, myself & others are talking about. The big “structural change” is the Roshei Yeshiva getting the students to date younger, even though it may hurt their own bottom line.
May the time come B’Karov.
As far as Gateways, they have a program in which a shaddchan is assigned to a specific community (similar to an idea you also had, IIRC), and works on the girls in the community. It gives the older girls more attention they would not be getting otherwise (such as a face to face interview). It’s almost like your “list”, but instead of the girls paying in, the community pays in. Either way more specific attention is given to girls that would otherwise be left out.
