I take those points (LLETSA+BA). It's easy on a thread like this to get into a false dichotomy, and Im definitely not saying there's just one side to it.
I do think that the "sizeable increases occurring also in Middle East and North Africa " (Arab Spring) has a lot to do with a growing sense that dictatorship doesn't wash any more - not that it ever really did - but the loss of fear/incredible bravery required to go and face the guns in places like Syria can't be put down just to living standards (aware that there have been food riots around the region) - it seems to me that people expect more, and are prepared to do what it takes to get it, and that's a real factor. Political aspirations are growing.
Supposedly there are thousands of demonstrations and riots in China every year that get little or no coverage. These tend to be explicitly about working conditions, but again, I think in China the cat is out of the bag, and people have a more general growing sense of entitlement, and are prepared to do what it takes to get it. IMO the Chinese CP's days must be numbered - I'd guess 10 years max.
There's also been a trend for regional self-determination (Scotland next?) in recent years, and I think that's connected somehow to this consciousness shift. Hard for me to say how exactly...
The effect of things like technology, communications, growing sense of individualism maybe, in the face of repression, shit living standards etc = the increase in social unrest, or more people struggling to get whats due to them. If you agree that the vast majority of things that have made the world better haven't been given from high, but been won, then this trend of growing social unrest can be seen as the next chapter in that process, and a positive thing.
Things are kicking off a lot more around the world right now, and there have to be factors behind that (
paul mason had a good stab at some reasons why < much clearer than in this post of mine)
I guess the danger is that the near future holds so many possible major upheavals that the any net gains are far out-weighed by the possible huge losses that might be incurred by major conflicts arising.
Hope that makes some sense...its late.
