Imagine yourself in an airplane flying over the earth. You are about to jump out and while your parachute is all set, you don't know in what kind of society you are going to land.
Since you might land in a spot that exploits or enslaves or oppress your kind, you would be well served to construct a society that is fair for all. The more spots you can safely and fairly live once you touch down, no matter who you are, the more just a world we have.
More or less that’s John Rawls in A Theory of Justice.
Increasingly, you are best served to fly past America.
Today I walked around Amsterdam with an energetic and courageous and idealistic young woman who wants to redefine success for all of us as she makes the world’s food systems more equitable and just.
Her ambitions and hopes were an inspiration and we need many, many, many, many, more of her.
