Karachi, the hub of economic activities, is under population threat as the city is overcrowded with people, eventually, increasing the pollution (waste, noise, water, etc.) levels in the city. Topped with weakening governance and least to zero maintenance.
Since independence, the city’s infrastructure is not yet fully developed, looking at other major cities, like Islamabad, Lahore, Multan, Peshawar, etc., they have developed tremendously, with better roads, at least.
One of the major turn-offs for investors is the city’s infrastructure, which is deteriorating continuously, becoming difficult for citizens to commute; eventually, businesses and investors (local and foreign) would stop investing in the city and invest in developed cities, like Islamabad, Lahore, etc.
