Lead
The lead has been substantially improved thanks to Saravask. However, the largely predominant image of Kolkata to the world is that of a city full of problems and sub-human conditions. Do you think at least one line highliting the problems of the city should be added to the lead? Like the slums/ poverty etc. I think so. However, I am finding it difficult to insert such a line appropriately. Maybe we can add it after the line that ends with "...the city is now experiencing economic revival." 

Please help! Bye.
