This is not just limited to this sector.
you can see
baap doctor - beta/beti doctor
baap banker - beta/beti banker
baap mill owner - beta/beti mill owner
baap lawyer - beta/beti lawyer
regardless of the skills of their offspring (which are busy partying hard anyway)
If you dig further you will discover that the offspring gets the job on "refererral" of their dad and not on merit. The MNA or minister referral results in a complete buffoon sitting on a decisive seat - and I mean buffoon with lower IQ than a chimpanzee
Sadly this is norm in Pakistan - even in winning work contracts, results are never required, only "khaao piyo, aur hum ko bhi khilao" is pressed.
