Should the United States...

...launch a new stimulus plan to rebuild its infrastructure? According to a piece in The Wall Street Journal by Ed Rendell and Scott Smith (my emphasis):

As recently as 2005, the World Economic Forum ranked the U.S. No. 1 in infrastructure economic competitiveness. Today, the U.S. is ranked 15th. This is not a surprise considering that the U.S. spends only 1.7% of its gross domestic product on transportation infrastructure while Canada spends 4% and China spends 9%. Even as the global recession has forced cutbacks in government spending, other countries continue to invest significantly more than the U.S. to expand and update their transportation networks. China has invested $3.3 trillion since 2000, for example, and recently announced another $105.2 billion for 23 new infrastructure projects. Brazil has invested $240 billion since 2008, with another $340 billion committed for the next three years. The result? China is now home to six of the world's 10 busiest ports—while the U.S. isn't home to one. Brazil's Açu Superport is larger than the island of Manhattan, with state-of-the-art highway, pipeline and conveyor-belt capacity to ease the transfer of raw materials onto ships heading to China.
