Farsi/Urdu linguist
Urdu has had a lot of influence from farsi to the point that its prestige language is farsi, the pakistani national anthem is basically in farsi. other than that a lot of the languages spoken in pakistan are iranian or indo-aryan languages which are mostly related to modern persian and middle persian so it makes sense to group them linguistically.
of course they can't use 'labor' without using 'demand' at least three words apart
