More recently we have learned that world record setting skyscrapers are planned for China and Saudi Arabia. World record setting skyscrapers are a indication of a looming world economic crisis. The Telegraph reports:
The Kingdom Tower in the coastal city of Jeddah will measure 3,280 feet (1km), some 568 feet (173 meters) taller than the current Guinness world record holder, Dubai’s Burj Khalifa, which stands at 2,716 feet (827 metres)
