Why are there so few rich, and so many poor? Why are modern education systems producing poorly educated children? Why is there hunger when there is enough food to feed everyone? Why are there still countries without social justice? We all long to feel safe and guarantee our children's future. For this, we must begin to practice mutual guarantee, by which all become guarantors of each other's well being. This book explains how each of us can relate harmoniously to the global transformation that is taking place.
