Query: Check out the archaeological record before...........

There is nothing dubious about the parallel of current events and the reason the Anasazi left Chaco. The archaeological record supports the decline of economics in Chaco. The Chacoans in power were trying many things to keep the "little guy" in the canyon while the infrastructure continued to collapse around them. Declining social economics and the environment overpowered the society's ability to continue as it had for several hundred years. We know Rome fell because their infrastructure failed. The people who survived were the ones not attached to the powerful elite and their technology. The efficient people survived. I strongly suggest people look into the archaeological data that is available to the public before stating things you know nothing about.
