Maybe Heinlein was on to something. In the book the only way to be President was to have a career in both the main divisions of their military and the only way to hold any office was to hold a position in at least one.

I say this as a person who never served. So this wouldn’t even really benefit me directly. Indirectly I would know that the people who rule us had at least once in their life not only do something for someone else but had a shit time of it
