[Futurama] Why was New New York built over Old New York instead of the old one just being demolished?

Wouldn’t have it been cheaper and easier to bulldoze the old one instead build over it? To build over first you need some kind of platform over the entire old city or did the old city sink like old Seattle present day? Even it had sunk they still needed a big platform over it since it sunk so deep. Filling it in would have been easier.

The way it works in NY is that if a developer wants to demolish a building, they have to get all the tenants out of the building first.  Usually, they'll buy them out for a generous offer, because most people are reasonable, but sometimes you'll get people who won't leave for anything, and set their asking price for millions or billions, so the developer has to pay their extortion fees, or wait for them to die. 

Well, for New New York, the developers realized a third option. It was cheaper to build a big ass platform over their heads than buy them out. So there you go.
