You seriously think that a draftee scrubbing floors somewhere against his will is more useful to society than a college graduate?
First, that is a false dichotomy. Not every loser who runs to Canada to avoid a draft is college material.
Second, even if we grant that a particular loser is / will be a college graduate, not all degrees are equal (1). I would argue that some degrees are harmful to society in and of themselves (2) or in the numbers (3) currently vomited forth by universities.
So, yes, a draftee scrubbing floors is a far superior societal contributor than many of the products excreted by the universities.
(1): Generally worthless degrees that only tell an employer, "I spent four years in college and wasn't too drunk most of the time to attend class." Examples such as mass communication, sociology, psychology, etc. The modern equivalent of a high school diploma in the 1950s and 1960s.
(2): Any of the degrees that fit the "<ethnic_racial_group>-studies" formula. Others include social work and the products of the anti-Western Civ Middle East Studies Association (MESA).
(3): Law comes to mind. By nature, the practice of law is at best a support function, usually is more parasitic, and very destructive to both those who actually produce.
