For the price of the Iraq War, we could've bought a brand-new Toyota Prius for every household in America.
According to the Census Bureau's projections for 2008, there are around 112 million households in America. (This includes family and non-family households.) MSRP for a fully loaded 2008 Toyota Prius is $23,770. Buying each household a fully loaded Prius would cost $2.66 trillion, which is less than Joseph Stiglitz and Linda Bilmes' estimate of over $3 trillion for the cost of the Iraq War.
