Pure rubbish.
India did not have any "industry" to inherit.
British deliberately deindustrialized India to keep it as a captive market for british goods.
It was illegal for Indians to start ANY industry without british permission.
That is why Gandhi started the movement to boycott british goods and asked everyone to spin their own cotton thread. Because even that was illegal.
Even making salt was illegal, hence the "salt march".
OTOH Karachi was the richest city of undivided India.
As it was then a Hindu majority city inhabited by industrious Sindhis & Khatris who created market & jobs throughout province.
In 1947, they kiIIed & kicked out these job creating Hindus.
Today, Pakistan has gone bankrupt. KARMA.
