The resources needed to satisfy all the want of human being are said not to be enough compared to all the want of humans we have many want we would like to satisfy at any given point in time which we may not be able to meet up with due to economic problems scales of preference simple is setting our needs inorder of priority.
Scale of preference and choice is a must in a world that is faced with a scarcity of resources. This scarcity is man-made because I think nature gave enough resources to each nation. But greed and materialism have made some people control these resources using the instrument of government or businesses connected to the government. These set of people make laws that will favor them and their cronies to enable them to have more access to financial power. An example is the intentional acts of the government of my nation to frustrate the businesses of other entrepreneurs because they want the business of their financiers to enjoy a monopoly. For one to survive in this world currently, financial planning is a topmost priority, except if you want to live on credit and loans.
