I got invited to a new years party thrown by a coworker. My gf had to work that evening, so she dropped me off on her way to work and was going to pick me up after her shift. This way I could drink and not have to worry about driving.
When I get there hang out and have a beer. Then my my coworker pulled the, “hey your good with computers right.” After spending an hour or two fixing his computer, I went to join the party. I didn’t know anyone there and no one would really even talk to me. Except this one huge guy who just kept wanting to fight me.
I spent most of the night sitting outside drinking by myself just waiting for my gf to get off work and pick me up. While waiting for her I drank more than I should have and as soon as we got home I spent the rest of the night puking.
In the military there are two separate classes, officers and enlisted. Officers had at least a bachelor’s degree and the military is a much different experience for them. They come in day as leaders, are paid significantly more, and have more opportunities to make lifelong connections with powerful people.
Enlisted are treated like blue collar workers, the grunts. Just in their day to day jobs enlisted people are going to have more wear and tear on their bodies. Take battle experience out of it, just as is, officers have a much better path forward.
Fraternization is illegal between officers and enlisted which basically makes it two segregated classes.
Enlisted folks also tend to come from lower income families, so while they are giving more opportunities than staying in their home town it can still be difficult for them to advance much higher.
In short, you have a large mixture of people from different ways of life with different education levels. Some take advantage of stuff like the GI Bill or other opportunities,. others don’t. Also some give their bodies to the extent that they can’t really function at the same levels on the outside.
