UK economy failed due to excess cleptocracy from very few, UK people start to be tired enough to riot. Perhaps they stop, perhaps they grow to the point of a full scale action against the government, I do not know, but that's to me an evident start/harbinger of a civil war.
The vast majority of impoverished people manage to get through their day without attacking a mosque. These people aren’t rioting because they’re poor, they’re rioting because they are racists.
If there’s a correlation between being a racist thug and being impoverished, the causation is likely low intelligence.
