In China, they're building infrastructure so fast it's crazy. Regardless of the different social and political systems, we just seem to have lost all ability to function as a society to create big things that we need. Imagine if we wanted to build something like the Hoover Damn today?
I have to assume it has something to do with half the population trying to actively disrupt anything positive the government wants to do, and if they can't completely kill the project, they try to profit off it as much as possible, essentially "proving" that government is inefficient, if not outright incompetent.
