Two things; this is interesting in light of the non-intrinsic value of gold (which yet has been historically valued--except when the choice was gold or bread, so to speak). We often forget that matter (we as humans, and speaking about a very broad time-base).

Secondly, the lack of tangible assets with respect to loans seems strangely coincidental [*in the sense of occurring at the same time, rather than the more widely accepted and inaccurate usage] with the growing absence of 'manufacturing'--from cars to fruit.

I'll note something but it's just at random, hopefully not related. A growing dearth of values has historically meant a dwindling of incentive. Few civilizations (city-based societies, that is) have lasted long and it was that which may have been the cause. Hopefully, in fact, I've just been hit on the head too many times and am rambling. However--are you still wondering what in the world could be attracting youth to ISIS?
