The overwhelmings number of shidduchim are not made by shadchanim. They are made by friends neighbors etc. Due to the inexquity of numbers the boys by and large have many shidduch opportunities (obviously there are exceptions but by and large) and therefore have no major need to go to shsadchanim they do not know.
The girls and their their parents are pulling their hair out and they will go to anyone and everyone in the hopes that it will result in a solid suggestion + a yes from a boy and hopefully a mazal tov.
JW22: I’m not sure what circles you are in but the boys by and large are getting married and they are getting married quickly. A study of Boys HS makes this point clearly. It is not yet complete but unless something changes drastically in the few schools that have not yet been vetted it will clear for all to see. The comparison of Boys alumni dating 5-10 years and still single vs. Girls alumni dating 5=10 years and still single is staggering. Stay tuned…..
