It very well could be NATO doctrine. Militaries figured out real quick that you have to keep troops alive long enough to fight. Whereas it seems civilian workers are treated worse.
Funny how the military, being an innately fascist system (meritocracy) also happens to be the most socialist system many countries have. Room and board, fair wages, a viable path to promotion, medical care all in return for your work and possibly your life.
The military radicalized me to democratic socialism.
