Sorry, the quote feature is giving me problems.
It's not a "give up" mentality but a recognition of what is coming. We are in a pretty deep hole and to a great extent there is nothing we can do about it. Its prudent to think about how to get through it on an individual basis.
The 1930's was very, very different in several respects. People were more self-sufficient, something like 60% of the population lived in rural areas and grew at least some of their own food. Many people didn't even have electricity or indoor plumbing, phones were not a household item, transportation was slow. In many ways, people had to survive on what they had locally. And the nation was not very dependent upon foreign nations for goods. The Great Depression was difficult, but many people had their own safety nets (family, community) to rely on.
Today, we are a service economy, not a production economy. Most people live in urban areas and are helpless without their electricity, plumbing, clean water tapped right into their home, gasoline, and food at the local mega-mart. People don't have their own safety nets, either. A person can't move back to their family farm like they could in the 1930's.
