Why wasn't mike stivic drafted in the service?

Mike Stivic, a character from the television show "All in the Family," was not drafted into the service primarily due to his status as a student. The show portrays the era of the Vietnam War, and Mike's academic enrollment provided a deferment that kept him from being drafted. Additionally, his anti-war sentiments and progressive views often led to conflict with the more conservative characters, particularly his father-in-law, Archie Bunker.
