ABSTRACT
Life is unfair. In many large cities, opulent homes can be found right alongside poor neighbourhoods. The new medicines that pharmaceutical companies develop are so expensive that many people can’t afford to use them. And while some people work all hours to get their job done, many others cannot find employment. Inequalities also characterize the lives of people in different countries. In some parts of the world, families flee hearth and home to survive; in others, people feel unsafe because they fear being burgled. Ice rinks are constructed in the middle of deserts for the entertainment of some. Yet many others are helpless in the face of natural disasters that destroy their homes and endanger the provision of food.
