Getting the nasty shadchanim under control will not end all shidduch problems, but it would solve some and it definitely has to be done…
Denying that these shadchanim exist doesn’t help the situation. If you never had to deal with any of them- I envy you. But they are out there.
I’m not denying it, I’m questioning the extent of it (I’m not saying you’re wrong, I’m just countering your bad experience with my good experience; I don’t think we can ever come to a conclusion on this), and questioning the extent that such an issue would have on the gender/age disparity issue.
