I would say that the one incredible thing that Karachi has going for it is the unabated supply of new migrants that pour into it day after day. It could be a poor factory worker who simply wants a job, it could be an ambitious guy coming for an education - they all add hope and vibrancy to the city. Now, this is not something that is generally taken as positive in Karachi. But the hope is that the migration that comes into the city replenishes its stores of resilience and energy.
