This book examines the four forms of wealth available to people, namely material wealth, spiritual wealth, natural wealth, and wealth of experiences. In the evolution of human society, the increase in material wealth has dominated, which is and has been the result of two main factors: consumer waste and the significant increase in population. Overconsumption and overpopulation have now become the two major problems of our time. These have brought our planet to its limits and have created the enormous ecological problems of our time. Future generations will face extremely difficult survival challenges.

The answer to these difficulties and the well-being of future generations lie in the significant reduction of the world population in the coming years and the limitation of consumer waste. Humanity must abandon the destructive effort of continuous growth, which is no longer possible, and adopt the model of a steady economy at a level of prosperity achievable for all future generations.

We can no longer live like Onassis, nor is it necessary to live like Saint Francis.
