identifying essentials and desirables

I recently accompanied a friend to have a look at the family of a prospective bride groom( for his daughter). I realized that many people are not clear in their decision making . Marrying off a daughter is one of the most important duties of an Indian parent.
As the alliance had come through the internet , the father wanted to authenticate the contents of the profile and also the get to know the family before processing further.

1. horoscope matched.( both were manglik)
   
2. Caste and region from which both families hailed was the same.
3. the girl is an MA (unemployed) and now doing teacher training and the boy is a B.com(accounts executive in apvt co) now doing MBA

In the end, he dropped the alliance after the visit due to the boy's job nature (unknown private co) and also due the monthly salary of the boy(Rs11,000 ).
This could have been done even without a visit.
The job security and future prospects of the boy and also the family status were cited as reasons.
what are the points to take as desirable in this decision and what are points which are essential?
I feel as follows(practically so)
some people still prefer govt job as an important factor in this decision but I disagree ,since now there are many avenues to growth in pvt sector also and job security lies in the merit of the person.
Essential

1. good family
2. caste /social status
   
3. horoscope matching
4. educational level of the boy and parents
5. job and future prospects of the boy
6. antecedents of the family/boy
   
7. economic situation of the families matching
8. boy and girl seeing each other and accepting
   

Desirable

1. nearness to native place in the boy's posting
   
2. property/assets of the boy's family
3. etc etc

if the essentials 1 to 7 are not cleared, do not even meet the people.
what do you feel?
have i left out anything?
