It's the NWO, run to your cellar and hide among your guns!

I think it's partly people wanting it to be like that and by putting it out there, they want to make it more likely by making people think about it.
I don't think they really have a vision or can see into the future, they just (over)interprete certain things and then think there may be a bright future ahead after some struggles.

In a way it's like a monetary replacement for religion I guess. Instead of fighting over theology, people shift to fighting over monetary systems and other ideologies that they expect to make their future bright.
As such I am rather neutral, I don't think such a change is very likely but neither is it impossible, things will develop, stuff will happen.
