Bruno, thank you for including me.
About trash, yes it is thrown overboard (with the exception of plastic). There are distances from land for each kind of trash. It you think about paper, that stuff will break down pretty fast. Metals will sink. There are some rules. Size is 1 inch pieces, and you really don't want to leave stuff floating. Food is also included in dumping. It's not a pretty side of shipboard life, but if there wasn't a way to get ride of it, you would be covered in trash pretty fast. Again, there are laws on what can be thrown out at what distance.
As for the "Drama" part of shipboard life. I think of it kind of like the reality TV shows...Big Brother or the Real World. On a ship you can't get away from someone that pushes your buttons, and the problems between you can build on each other. There are personalities that conflict on any vessel.
As for the officers and chief's lives, yes, I would say they are probably more comfortable. There difference is a little more defined in the Navy (they're even color coded, kaki or blue), but a majority of non-rates will have undersirable jobs. Until they make rate, they will be doing many of the same tedious things. Even after they make their rate, some will not be happy. Officers have a lot of paper work each day, in addition to managing their divisions or departments. Paperwork gets old, especially SF-4910s, but stuff has to be done. Eating in a wardroom v. eating on the messdeck is better too, where the food is served too you...however, there are also rules to the wardroom, so generally is it more fun to eat on the messdeck and speak your mind.
I'm currently underway, and I haven't been able to watch Carrier. I heard about it before it came out though.
Maybe I'll catch the reruns!
