My cousin just got married at 23 to the first boy who ever gave her a yes. Hard to say no when you're not getting yeses from boys.
Is 23 a tragedy? No. But it's a challenge that is perpetuated by the current system and, empirically, seems to be worsening.
You're highlighting results of issues in the current system, which are what they are. I don't dispute the issues. I don't pretend to have any answers, either, because my opinions on what the standards should be are irrelevant to anyone but my own family.
My aunt who is a professional shadchan says she has 30 girls' resumes for each boy. Take that as you will.
That's an interesting anecdote, but I don't know what to do with that information. Is she an outlier, or are the same numbers found by other shadchanim as well? If other shadchanim have more balanced ratios, then she should probably change whatever it is that she doing to collect resumes. If all shadchanim have the same issue, why are boys not submitting resumes? Are they handling the process themselves? Are their mothers handling everything? Do they feel like they don't need to put out resumes because girls will come knocking anyway?
