Final answer:
The question discusses veterans' preference and how the Vietnam War draft disproportionately affected lower economic classes and minorities, leading to the conflict being characterized as a working-class war.
Step-by-step explanation:
The question refers to the notion of veterans' preference, which is often related to benefits or considerations given to individuals who have served in the armed forces. During the Vietnam War, the draft meant that many young men were called to serve, particularly affecting those from lower economic classes and minorities. It is noted that people from higher economic statuses had ways to avoid military service, thereby leading to a disproportionate representation of disadvantaged groups on the front lines. This disparity highlighted socio-economic inequalities within the draft system and military service obligations, resulting in Vietnam being termed a working-class war.
