  1. Economic systems can change quickly and unexpectedly. Slavery, once seen as essential, became morally wrong in a short time due to various factors like economic shifts and the resistance of enslaved people.
  2. Today's society faces a similar situation with climate change and inequality. Current systems are proving unsustainable, but many individuals and countries are hesitant to change because it might mean losing out in a competitive world.
  3. Younger generations are more open to alternative economic models because they haven't built their lives around the current unsustainable practices. If we act now to create and share new ways of living, we might be able to make positive changes before time runs out.
