That said, people will come around when they have to, and not a moment before.  Everyone has a different comfort zone with regard to facing truth; the art is to find that zone, and push right to the edge.  If you want to know the absolute, dead worst that can happen, read about Easter Island.  I used to think that scenerio was unavailable to us but I am no longer so sure.  Every step we can take away from that outcome we can count as an actual plus.  

At this moment, Cuba is our foremost example of successful, sudden de-industrialization, but its political system, which played a key role in the process, is rather unique.  "Success" not in quotes, because they avoided outright starvation--it doesn't get much better than that.  

No matter what happens, the world will become local again.  Europe perhaps less so than the US, since you have functioning rail systems that will be usable well into the crisis.  Still, the point is that the essentials of life, such as food, will consist of that which can be obtained locallly.  This is why organic farming is so important (industrial agriculture is going down soon) and permaculture is a beacon of hope.  

Political chaos is sure to ensue, and only robust, local social structures have any hope of surviving this.  The essential nature of this chaos will be people grabbing what they can to maintain their past ways, and thus sealing off their own and their neighbors' futures.  It will happen:  Once you have dealt with the basics of survival, it is the biggest threat, and can undo everything.  (A typical example:  Right now the city of Los Angeles is trying to shut down community gardens and take the land to build more freeways.  The gardens will determine whether people live or die, but before it is finished that freeway will be useless.)  

The US--because of its more extensive wrong choices--will be going down before Europe, so you will get lots of case studies from us what not to do.  

The Fates are kind.
