The draft is not what will happen. In Vietnam they've already figured out the downside of having middle class and upper-middle class kids serving as enlisted people in the military.

                   What they will do in the future, for purposes of increasing numbers, is hire more "security" folks from contractors like Blackwater and use more and more of them in combat. That way they don't have to worry about a backlash in the states. The only people getting killed will be mercinaries and poor folks.
