One way to look at Occupy:
It's an attempt to build a global political feedback loop for an open loop global economic system.
This is a little heavy with engineering speak. Here's a simple example.
- System: How you drive your car. The car is propelled forward. You see the road curve. You turn the steering wheel, the car turns to follow the road.
- Open loop system: A system without a feedback loop. How you drive your car with your eyes closed.
- Feedback loop: Visual input from your eyes.
