Isn't doing more of something and expected a different result the next time considered to be a sign of insanity? Japan engaged in monstrous infrastructure projects, but ended up with just "the lost decade".
from Bloomberg:
(Bloomberg) -- The U.S. should consider drafting a second stimulus package focusing on infrastructure projects because the $787 billion approved in February was “a bit too small,” said Laura Tyson, an adviser to President Barack Obama.
The current plan “will have a positive effect, but the real economy is a sicker patient,” Tyson said in a speech in Singapore today. The package will have a more pronounced impact in the third and fourth quarters, she added, stressing that she was speaking for herself and not the administration.
