Consider that, according to sources like Columbia's Jeffrey Sachs, the Worldwatch Institute, and the United Nations, with that same money the world could:
Eliminate extreme poverty around the world (cost $135 billion in the first year, rising to $195 billion by 2015.)
Achieve universal literacy (cost $5 billion a year.)
Immunize every child in the world against deadly diseases (cost $1.3 billion a year.)
Ensure developing countries have enough money to fight the AIDS epidemic (cost $15 billion per year.)
In other words, for a cost of $156.3 billion this year alone – less than a tenth of the total Iraq war budget – we could lift entire countries out of poverty, teach every person in the world to read and write, significantly reduce child mortality, while making huge leaps in the battle against AIDS, saving millions of lives.
