In my opinion I think that America won't build a space elevator. I think Dubai will build it because America does not have the ambition to build tall things like Dubai does. Dubai's skyscrapers are like 100 years ahead of its time and the rest of the world including America. Burj Dubai-950 meters, Mubarak Tower- 1001 meters, Murjan City Super Tall Tower-1,022 meters, Al Burj-1200-1600 meters, AL Jaber/Ethic City-1,852 meters. America, Empire State Building-381 meters, Freedom Tower- 541 meters. You see the difference. America is one century behind Dubai when it comes to technology and skyscraper so Dubai will probably be the only one to build a space elevator this millenium. America might build one after the year 3,000.
