I think he might have been trolling. Certainly, I don’t think shadchanim who “spend every night” on shidduchim “average only a few shidduchim a year”, IF they are successful ones.
And all that nonsense about wealtyh people being too busy enjoying their wealth…
As far as needing more shadchanim, this has been mentioned as a problem in the public sphere. Hasn’t everyone seen the calls for everyone to spend an hour on shidduchim a week, or something like that?
