Is the fear factor holding back US government spending?

WIth interest rates so low, governments considering a proposal to build, say, a new highway, should regard this as an ideal time

In his first inaugural address, during the depths of the Great Depression, US President Franklin Delano Roosevelt famously told Americans that, "The only thing we have to fear is fear itself." Invoking the Book of Exodus, he went on to say that, "We are stricken by no plague of locusts." Nothing tangible was causing the depression; the problem, in March 1933, was in people's minds.

The same could be said today, seven years after the 2008 global financial crisis, about the world economy's many remaining weak spots. Fear causes individuals to restrain their spending and firms to withhold investments; as a result, the economy weakens, confirming their fear and leading them to restrain spending further. The downturn deepens, and a vicious circle of despair takes hold. Though the 2008 financial crisis has passed, we remain stuck in the emotional cycle that it set in motion.
