Be careful, it wasn't the current Chinese regime that executed the rash of infrastructure improvement projects in Hong Kong in the 90's. In fact, the vast majority of the projects were initiated and executed by large British engineering and architectural firms to milk as much money out of building projects prior to the turn over to Chinese rule in 1999.

I didn't even want to make any claims about China. Maybe the super airport makes business sense. Just saying that a pretty appearance doesn't prove that a great economy is behind it.
