Digest it butthurt, Orangi is the largest slum in Asia.
We will make our financial capital into World Class city because slum rehabilitation is in full swing, Pakistan could uplift 3-4% people out of slums in 20yrs India did 20%, so Karachi will remain a Megaslum and Mumbai will get rid of its all slums. Apart from this Mumbai is getting Second Airport, Monorail, Metro Rail and Bullet Trains, Superslum Karachi will never match that.
Do you how Slum rehabilitation being done in Mumbai, Builders make a deal with Slum dwellers to sell their land, builders will construct houses for slum dwellers in part of the land and in remaining area construct skyscrappers. Mumbai's current highest building was constructed on same model.
So, by 2030 India will have 4-5% population in Slums and Pakistan track record shows it will be 40-44% by 2030.
