Planet Money reported recently that the $1.3 billion in military aid that we send to Egypt every year is being wasted. All of the money we give them is to buy military equipment from U.S. manufacturers. Much of what they buy is duplicative and excessive for the Egyptian military and is simply being stored in crates. The primary reason that this continues is that U.S. manufacturers lobby Congress for it to continue, and Congressmen and Senators want to keep the jobs and money flowing into their States.
