David--not sure how this is relevant, but I graduated high school and entered college when I was 17 in 1967. This was at a small university in deep East Texas, near Willie Brown's hometown. In the spring of 1968, I was sitting on the front porch of my dorm watching the girls walk by when my roommate interrupted my reverie by waving a section of the Dallas Morning News in my face. I asked him what could be more important than watching some of the most beautiful women in the world walk right by our front door. "Mike", he said, "have you ever heard of Viet Nam?" "Of course" I said. He said, "well do you want to go? Not especially" I said. "Well, find your birthday in this article on the Viet Nam lottery. If you're number is less than 181, you're going". "Holly Cow, let me see the list". I had a draft card but never thought much about going to war. My number was 183, my roommates, 79. I finished school, and he enlisted. I ended up getting a Ph.D. at Texas Tech well after the war was over, but some of the people I knew in Nacogdoches at Stephen F. Austin State University went to Viet Nam and never came home again. What are the economics of that?
