Probably because its not the same at all. Getting naked and spreading your legs is neither as productive nor difficult as serving your country. Neither should it have the same social status.
We have different moral compasses, I guess. To me, obeying military orders (which often result in killing people) is neither productive, nor difficult (as a big part of thinking/initiative is replaced by blindly following orders). Military personnel basically outsource a large chunk of thinking and assessing good/bad to a "higher power". In a way, that's very easy and comfortable life for a specific type of people: all higher order judgments are deferred to higher ups in the military chain. Besides, I wouldn't say military personnel are "serving" their country more than, say, plumbers, electricians, railway workers, postal service, healthcare workers, or, even sex workers.
> Neither should it have the same social status
I disagree. The fact that somebody who has no other skills and initiative but to be a death machine/robot blindly following orders, doesn't warrant them to be a hero, and sure as hell doesn't qualify them to a high social status in my book. And, at least to me, calling military service "productive" is just plain hypocrisy. Their only function is to either destroy things during war, or sit around looking menacing when there is no war.
Imo, money spent on weapons and the military could be better spent to build more social housing, solve healthcare problems, etc.
We don't give high social status to killers, thugs, murderers and hired assassins, but when it's institutionalized killing, (which is the military) that's okay? The fact that an "official" gives the word, and the victims are not citizens of your country doesn't make the military be less about killing.
There also is nothing "productive" about paying for salaries, equipment and training to a bunch of grown men in the anticipation that you have to send them to do violence to your bidding.
If the military was not under the veneer of "official", wrapping it in an "institution" and all the language of "serving your country", we'd not been able to distinguish between military, militia and armed thugs.
Yet, our society at large reveres them as some heroes and they are mainly socially acceptable.
I bet that if we had a "Department of pleasure", with ranks, hierarchies, rules, promotion paths, etc, sex workers wouldn't be as marginalized as they are now. In fact, in many civilized countries, prostitutions is both legal and taxed, and less stigmatized than it is in the US, who are too puritanical/religion influenced in their views to want it to be otherwise.
I disagree. First and only rule of nature is might makes right, and being capable of dishing out the most violence (and hence also least likely to be the victim of it) is very “productive”. It is a huge contributor to the purchasing power of the US dollar, which is a referendum on the stability and productivity of US society.
For example, the oceanic transportation routes around the world are kept mostly safe and humming along because of militaries enforcing it.
In an ideal world, 100% yes.
In our world, where every now and again a crazy power-hungry dictator appears and wages a war against a weaker country and is killing civilians - unfortunately it's a comfort we can't afford.
With the risk of being political, I see nothing "defensive" or moral about the military, even in the most advanced nations that are supposedly paragons of human rights.
Take the "dictator attacks weaker country" narrative. The NATO defensive alliance fits this narrative by providing weapons and military training to weaker Ukraine so it can defend itself against the aggression of bigger Russia. On the other hand, the same defensive alliance has no scruples to providing weapons to Israel so it can wipe out and cause immense suffering and casualties to Palestine, a weaker nation.
Which brings me to my conclusion that there is nothing inherently moral about the army, it's just a blunt instrument to do the government's bidding. Hence, I don't see military as our "protectors", but as the government's institutionalized thugs. I also don't see a reason for them to be lauded for their actions, as their actions are often immoral and sinister. I am talking things like the military secrets Assange unveiled, or the illegal treatment of prisoners in Guantanamo, or the sometimes indiscriminate bombings of civilians to hit 1 potential target.
And since they are not protecting me but the government's interests, I don't see a need to thank them for their service more than I see the need to thank bouncers at a disco I don't own for theirs.
