The real currency here isn't just fiat it's trust. Trust that your sacrifice means something. Trust that your family will be taken care of if something happens to you. Trust that the cause is legitimate.
This is the importance things we should talk about because some soldiers go to war and unfortunately for them they never returned and their families left alone with nothing. Actually the government is supposed to do something about it but some of them don't, knowing fully well that they have no one else to look up to. However I think there's a lot of politics going on in different sector inside the military, some never go to war and they get the bigger salary and if anything should happen to those big guys on the military, there families will be properly taken care of but not like that down to the list of the soldier. However, it seems of the soldiers don't do the job because of the money buh because they love the job.
It is very true that there are many opportunities that need courage, but not every person who makes such a choice will be compensated right. For instance, people who engage in challenging a situation or taking up complicated work, have motives apart from incentives. However, they are not equally rewarded and there are various factors that intensify this episode. There are such means or processes, but they are deficient in most cases and therefore do no justice to all the parties involved. People expect those who devote themselves would be safer, but such expectation is not always manifested.
