Realistically NYC is as large as it is going to get, in that it has shown itself to be a product of a bygone era and has been surviving on that image. 2020 shows that it was unsustainable and as we move forward, it continues to make bad choices with its budgeting and taxes. We don't need mega cities, least not one that is 110% predatory. The money sloshing around there is better spent else where unless you're trying to launder it.
