Why master of commerce or business administrator is not given too much employment opportunities in developing countries?

I think that the problem is the number of candidates, there is so much graduates person who got those kind of diplomat around the world.

No offense, MBAs graduated from highly International recognized institutes are given preference such as Henley, Oxford or Cambridge Universities.

there are two reasons 1st job oppertunities are limited due to economic conditions.
and due to1st reason the more qualified people are applying for same job as they are not getting the job according to their competency level.
