Kuwait would have benefited from a stricter building height limit. When a city tries to spur development by removing height restrictions the result is usually the opposite. Landowners end up waiting to sell as prices skyrocket because of speculation. The few skyscrapers that get built suck up all the density and leave the rest of the urban fabric with far less demand. You end up with a few shining gems that stand tall amongst impoverished neighbors.
Washington, DC, is a great example of a low rise city that is very dense. Kuwait really had no justifiable reason to start building forty, fifty level towers. It would have been far more beneficial for everyone had this development been spread out over a larger area of Kuwait City. Instead of a few shining, glistening, resource draining towers built by a handful of developers, we could have had hundreds of four or five level mixed use developments. That sort of democratic urbanism would generate a richer urban environment.
