I don't know if Fiat users are mentall ill, maybe institutionalized is a better politically correct term.
Institutionalized is just a clever euphemism for indoctrinated. This is abusing language to avoid facing the obvious ethical horror of socially engineering children during formative years.
You have been lied to your whole life, by people who have been lied to their entire lives, and so on, generation after generation, because of a continued failing of basic ethics.
Yes, that could be a better term for it, Indoctrination. Generations upon generations being told what is "money" and trust the central authorities in place.
If you're not a self thinker, and believe everything that's written and spoken on the boob tube, then sure this can be dangerous and unexpected when something like Greece happens. If you can form your ideas, and see the big picture, then nothing that will occur soon should come as a shock, when the mighty Fiat finally succumbs...
