This is satire, right? NYC is located at the mouth of the Hudson and one end of Long Island sound, two relatively sheltered waterways. For hundreds of years this facilitated huge amounts of resource extraction from the region. Upon this resource extraction economy resource processing was built. Naturally it was located where the labor was the the products flowed through, the port. From there industrialization and an industrialized economy way built upon the resource processing. Through little other than historical luck of geography of the industries (that really took hold in NYC was finance. It has been that finance industry that has carried NYC through the transition to a service economy. So basically, NYC is valuable today because it was yesterday and if you follow the recursion back to the base case you find natural resources. While the natural resources are now gone or irrelevant they were the startup capital for the NYC we have today. There is no inherent value to a mass of people unless there is some productive activity for them to engage in. NYC got lucky and developed a finance industry. See Detroit for what happens when you don't make the transition.
