Paul and Sarah Edwards are authors of a timely book "Middle-Class Lifeboat: Careers and Life Choices for Navigating a Changing Economy." In a world of decreasing resources, they ask, how do we financially support ourselves while moving towards sustainable lives? Emphasizing independent income sources, they consider dozens of possible careers from basic services to local-scale technologies. Life choices include lowering costs through simplifying, getting out of debt, and demonetizing (e.g., bartering). Or one can consider an "off-the-map" lifestyle like living abroad, off-grid, or an intentional community. This downturn is not just a cycle, they emphasize: it heralds a sea change.
