Re: Changing Pakistan’s national language?
The strongest argument against that is the fate of Bangladesh. Fluent knowledge of English is limited to a very small proportion of the literate population, because Bangladesh uses only Bengali for educational purposes. This makes Bangladesh less capable of competing in the globalised services economy.
Pakistan has a rapidly growing services economy because most of the educated people in Pakistan have strong English skills due to English-medium education at schools and especially at universities.
Removing English from extensive usage will economically and academically isolate Pakistan as Bangladesh has experienced.
One of Pakistan’s economic strengths is the presence of a large English speaking workforce due to the strong emphasis on English medium education.
