There is an interesting factor in all this that might become very useful were it more widely known.
There is, within the US, a sense that the American soldiers thrown into combat or even into the sort of slaughter that we apparently have here deserve some sort of reward from the system that they bought into. We find, for example, that it is offensive that the US government performs invasive and dangerous experiments on military personnel that generally cannot sue, and that damaged youths who signed up as heroes are mostly brushed off as the dregs of society when the rulers find it convenient.
It is worth knowing that the American and allied recruitment of ISIS members happens in very much the same way. They are led to believe that they do something heroic. For the most part, they either fight for a cause or excuse their violent vices with a cause, just like American soldiers.
Very much like American soldiers, they are regarded as expendable. There are some differences in that they are regarded as more expendable, but this is largely a function of the different cost of the public relations, since the ruling class is more extensively dependent on the relative good will or passivity of Americans and Europeans than that of many nationalities.
But the different PR status of ISIS fighters is rather stark. As happens with other mob assassin types sometimes, their employers actually get a PR boost from their slaughter. The game then becomes paying one group to slaughter another until a supportable fiction is arrived at.
We all might want to take this sort of thing into consideration as we “strive to be productive members of society,” in whatever sense each of us think of that. There’s really not much call to be working for these people.
