I haven’t read the letter……………………
BUT, many a shadchan gets paid when a marriage takes place after the introduction.
The shadcan may have worked many hours to find a suitable match. The client may have needed to date many potential mates before a successful match was made. Then the hourly rate is far lower than a case where the Shadchan spends 1/2 an hour with the girl (or parents), 1/2 an hour with the boy (or parents) then makes one phone call to set up the date…the couple hit it off immediately, both sets of parents approve and a chasunah results. The hourly rate can be very high.
The psychologist has a static hourly rate and collects for each 50 minute hour that a patient is seen.
So if a Shadchan gets $2000 for a marriage and it takes 2 hours work, the Shadcan makes $1000 per hour before expenses. If it takes 40 hours work over 6 months to a year, the hourly rate is only $50
The Psychologist may be billing $125 per hour. If the therapist takes insurance the actual rate they receives may be as low as $35…the rest is written off. The psychologist has to work and bill 16 hours to a private pay patient to earn the $2000.
