It looks like the US spent $420 billion on defense, not including a lot of other stuff, some supplmental war thing and then I hear defense spending is snuck into NASA and no doubt other stuff. What is this money spent on exactly? Like how much is wages for the people who work, how much is for treatment of people injured in war, how much is for airplanes, boats, gasoline, buildings to do research in... anybody have a general idea of where the money goes specifcally?
