Not only is our world one of limited resources, the resources we do have are unevenly distributed. No two pieces of land are equal in terms of utilization. Some plots of land have multiple utility. Some are near water or receive rainfall. Some are not and do not.
Some land contains minerals, oil, metals and various chemicals.
Some is apparently barren in terms of our present knowledge and technology. The person receiving a few acres in the middle of the Gobi desert has a high probability of dying of thirst. The person receiving a few acres in the middle of Beverly Hills might do very well indeed. The same diversity of distribution we find in land resources is found with human resources. Human beings are unevenly distributed about the globe.
