I’d almost certainly have wound up in WWII. I’d have been 17 when Pearl Harbor was attacked, and would have graduated 6 months later.
Tough call on what would happen, though–I don’t know enough about college deferments, etc., during WWII. My father was career navy, then a doctor, so let’s assume the same. Mother also navy, also a nurse. Both officers. (Well, I guess my mom wouldn’t have been, right? Were there female officers in the WWI era? Weren’t they all just support staff, not actual military?) They would want me to go to college, but they would also expect I would serve. And they’d want me to be an officer, rather than enlisted… So what happened if you were in the middle of college and got drafted? My expected graduation date would have been in summer 1946. If I got a draft notice my sophomore year, would I be allowed to defer until I was finished college? Would I be allowed to go to OCS even if I hadn’t finished my degree?
Looking at the wider picture, if I lived through the Depression, I would almost certainly have chosen a more “practical” college track: science and engineering, rather than writing and art. (My grades in the sciences and my SAT math scores were good… I just would have had to work my butt of to figure out calculus, which I dodged in high school.)
I think our family would have done relatively well through the Depression, still, with my father as a doctor. Although, actually, now that I think further about it, we might have been really screwed–my dad had Parkinson’s. Without modern meds, he might very well have been dead (and certainly retired) before I graduated from H.S. My mom probably would have been working to support the family, and my older brothers might not have left home; they might have stuck around to help out.
But at any rate, I did get a full scholarship to school, so assume that’s the same. I can’t pass up the chance to attend college for free, so I don’t enlist right out of H.S., I go to college. The war is on. Then, let’s assume I get drafted midway through school. If I’m allowed a deferral, I stay through until I graduate, at which time the war is over. I still probably join the Navy, but maybe I work on research (Penn State had/has a significant Naval research dept., where they worked on torpedo design, acoustics, etc.). If I’m not allowed a deferral, I join the Navy (or wait… can you not choose your branch of service if you’re drafted? Are you just thrown into the Army?). Wind up in the Pacific on a ship, hopefully don’t get blown up.
Actually, another thought occurred to me: It would have been far more likely that I would have gone into medicine, with my father being a doctor and good work being so dear when I was growing up. So instead, I’m going to college for biology on a med school track, and if I’m drafted and can’t defer … do I become a Navy Corpsman? Then I probably wind up in the middle of the Pacific island battles with the Marines, and may or may not survive. Yeek.
