Of course the article shows its bias more clearly here:
> Whether in the US, UK or elsewhere, the more dissatisfied and afraid people become, Homer-Dixon says, the more of a tendency they have to cling to their in-group identity – whether religious, racial or national. Denial, including of the emerging prospect of societal collapse itself, will be widespread, as will rejection of evidence-based fact. If people admit that problems exist at all, they will assign blame for those problems to everyone outside of their in-group, building up resentment.
This is using a lot of loaded language to suggest that it's primarily the right guilty of these things, but identity politics is a mainstay of the left, at least in the US. Could it be that eliminating identity politics is more important than redistributing wealth?
