For the price of the Iraq War, we could've not only fully funded One Laptop Per Child, but expanded its mandate to cover all humans, sheep, pigs, and cows.
There are about six billion humans, 1 billion sheep, 1 billion pigs, and 1.3 billion cows on earth. OLPC is producing laptops at $175 each. Giving these 9.3 billion organisms their own laptops would cost 1.63 trillion, which is less than Joseph Stiglitz and Linda Bilmes' estimate of $3 trillion for the cost of the Iraq War.
