Many male engineers from top colleges marry very beautiful women, who may not be very intelligent
A very beautiful wife is considered to be a status symbol , trophy for the man who is marrying her, and many of the male engineers from top colleges in India are marrying very good looking women, as they get many proposals from good looking women and their families
However these women may not be very intelligent, and as a result, the children of these male engineers from top colleges may not be very intelligent as it is widely believed that intelligence is at least partly inherited from the mother
Many of these male engineers have a high IQ, and having a child with a high IQ is also considered a kind of status symbol in India.
So when the child from the beautiful wives of these engineers is not very intelligent, these selfish engineers try to get a child through surrogacy
