But, one day Joe Blow gets promoted. Same guy, same talents, same personality......but now he's a lieutenant. And NOW he magically rates being addressed as 'sir'. Lunacy.
Western militaries derive from a tradition in which officers were landed gentry at minimum, and enlisted were not. Americans seldom get that the distinction and related courtesies, stem from a society in which officers were nobility. That is btw why the Americans were the first to make a four year degree a prerequisite for commissioning: their caste system is based on schooling, and only indirectly on descent.
So it doesn't need to make sense, any more than curtseying to Eugenie York but not a commoner with vastly more intellect and accomplishment makes sense; it's an artefact of a different culture. Do you worry about whether it makes sense that some cultures have shrines to dead relatives in corners of the home, and it matters intensely *which* corners? If you treat the military as a fascinating but markedly different culture, it might not drive you as crazy. That's how I live with it, anyway. *drinks quietly*
