This book proposes a new solution to the problem of the migration crisis engulfing the world by creating safe harbours, or Free Global Cities. In the face of the largest displacement crisis on record even the most optimistic view of the future suggests that in the years ahead, more and more people will migrate in order to survive. The world requires places where refugees and other migrants forced to leave their homes have the opportunity to work, study, create, start businesses, and rebuild new lives for themselves and their families. Free Global Cities can deal with this growing global crisis in a completely new way. They are autonomous, self-governed subnational entities that provide a safe environment and rule of law that will create wealth and prosperity for its residents as well as for the nations hosting them. Such a model would contribute significantly to handle the largest migration crisis in history, which the world will be experiencing in the coming decades.
