Planetary alignments are not so rare as the con artists who right such trash claim.They have happened in recent history and no planet wide disaster ensued.As to capitalism you may not like it but it is the most efficient way of running an econimy,it does on the other hand require firm govenance to keep it under control ,the worst problems tend to start when some idiot says hey all these regs are getting in the way of buisness lets get rid of them.
To even take this topic onto a more "conscious" level. If you liked Collapse. Do your mind a favor, and read Daniel Pinchbecks "2012 return of Quetzalcoatl". It's a heavy read...big time. It will turn your brain inside out to the possibilities in our future. Most people freak out about what may come in 2012. We know the planets will align, but I say... don't fret. Be positive. Our minds as a collective conscious have the ability to create our collective path.

Adopting a self sustain life style is just one part of the puzzle. Mankinds ability to grasp materialism with both hands is and will be our down fall
Make meditation a part of your weekly activities, and think good thoughts. We all know capitalism, and materialism is a dead end street. So, meditate on a bright more conscious future for us all, and our children.
