I'd put it either in Hong Kong, Shanghai or Manhattan.

Hong Kong because the land is so expensive there that it really is the most financially feasible place for a mile high tower to get built. If I'm not mistake HK is home to the most expensive land in the world so building way up is a necessity.

Shanghai because its quickly becoming the skyscraper capital of the world. The supertall trio there is absolutely beautiful and something twice the size of the Shanghai Tower could be a aesthetic reality one day.

New York because it is so vibrant, dynamic and beautiful. What has housed a dozen world's tallest titles deserves to hold one more.

That being said I think the first mile high tower will be built in Dubai or somewhere else in the Middle East. They know nothing, but excess when it comes to skyscrapers.
