The Wall Street Journal comments: "Even the harshest critics of authoritarian rule generally concede that when it comes to building infrastructure China wins hands down over the rich democracies. America has practically given up....Meanwhile, China can't build fast enough....But at what cost? A report by four academics at the University of Oxford's Saïd Business School has created a stir by arguing that what outside observers often hail as a towering strength of the Chinese system has instead led to colossal waste....Examining data on 95 road and rail projects, the authors say cost overruns are typically about the same as in democracies, and although China handily wins on speed it comes at the expense of quality, safety and the environment...If these failures are representative across the board, they not only suggest a Chinese financial blowup but challenge a conventional belief that the more you build the more you lower costs for businesses and households and add to economic growth. In China's case, infrastructure may be the road to ruin."
