As for your statement above:
“That the BIGGEST (not only) backlog is a -> b.”
Perhaps, just maybe, possibly, it might part of the reason, why that backlog exists is because of the observation i pointed out above.
I mean it’s not conclusively proven, but maybe just maybe if the number of unmarried guys and girls were relatively equal and the guys didn’t have the upper hand, and thus the guys wouldn’t be able to be so selective, and the shadchanim wouldn’t be so beholden to the guys, etc etc… maybe just maybe that might alleviate and smooth step a->b.
I mean it’s just a guess – some food for thought.
I mean if you have 100 girls and 10 guys and the guys have many many options it’s likely and natural that there will be a backlog from a->b
but as I’ve stated numerous times above, this isn’t a dialogue i’ll have in this forum at this time, it’s just some food for thought.
