Of course:
Off the top let me state clearly, I am not a shadchan.
Having been heavily involved in the issue for the 3 years and counting, and having been in frequent contact with tens of shadchanim as well as parents and singles in the parsha, allow me to point out the inaccuracies of your comments as well as make suggestions as to what actually works and what doesn’t work.
1.Shadchanim don’t return phone call.
The shadchanim you refer to receive 100 new phone calls a day. They are empoyed by no one and have no secretary. Do you think it’s feasable to return all the phone calls? Do you thinks it’s even smart. They call the people that they have tachlis to tell. Obviously someones getting calls, they are setting people up and people are getting married.
Here a little experiment. Ask those shadchanim who you are lambasting for a list of the shidduchim they have made in the last year or two. I can gurantee that the overwhelming majority of the girls whose shidduchim they have made would perfectly fit your description of regular nice middle class girls.
BY FAR the overwhelming numbers of shadchanim are kind and genuinely trying to help whomever the can and are fair minded.
4. Impossible to get a Shadchan list
5. Shadchanim today work much harder for their rich clientele than the middle class, see what I wrote to question number 2.
