You’re missing a critical word- “there aren’t enough COMPETENT shadchanim”. Increasing the number of untrained shadchanim will just exacerbate the situation. Increasing the number of competent shadchanim while getting rid of the ones who shouldn’t be in the business in the first place would be a great start to solving the crisis. (Although there are many, many other factors that will need to be addressed.)
You can count me and my wife as a shidduch that was made by a family or friend- we were the only successful shidduch she ever made. After a suffering a horrific incident at the hands of a cruel “professional” shadchan I decided that under no circumstances would I ever use a “professional” shadchan again. Guess what- a family friend who was being pushed out of the way by the ruthless shadchanim was finally able to set me up with my wife and the rest is history.
I’m all for people relying on friends and family to set people up and a permanent ban on professional shadchanim. There’s a difference between a friend or family member who dabbles in shidduchim verses a shadchan whose only training and experience is that they “dabble” in shidduchim (i.e. the arrogance and lack of basic decency that comes along with being a “professional” shadchan).
