This seems like an impossibility though. Take land for instance. There's a finite amount of land on earth. If 8 billion today own all of the land there is on earth, and in 2060 there's now 13 billion people, how are these 5 billion new people going to own land (when all of it is already owned by the other 8 billion)? For the 5 billion new born people to acquire land, means some previous owners must lose ownership of some of their land. Put it another way, if we divided land equally amongst all human beings, with every birth, the amount of land per person will decrease, which means the sheer birth of humans makes us poorer when it comes to the amount of land we each individually own. Heck you can apply this to most anything. Take iron. If all the iron on earth has been mined and been used to construct steel buildings and cars, and I want to make a new car made of steel, then I would have to dismantle an existing car or building in order to acquire the material to do so. Only reason this doesn't happen today, is because there's still more iron that we can mine out of the ground; I'm not yet forced to "mine" it out of my neighbor's car.
