Scale and our incomprehensible economy

One of the reasons why small scale is so important is because it keep things things comprehensible. One thing the economic downturn has revealed beyond any argument is the fact that no one understands our economy. The scale is too large and there are too many things going on as a result. How do I know this? I know this because every time an expert speaks he doesn't agree with the last one. It's clear from how the government is reacting (and how fast people are changing their minds) that we are in uncharted territory. There are many economic theories that are being tested and are coming up short. We are so full of ourselves we think that the shear scale proves we are something special. We're not. It may finally be coming to an end. In any case, it's time to move to a community based economy. Two great ideas are LETS (Local Exchange Trading Systems) and local currencies like the one in Ithaca, NY
