Two different economies

   The economy is the science that is responsible for studying the processes of scarce resources that are needed to survive in a society, these resources are: food, clothing, housing, technology and basic services such as drinking water.The minority of some countries enjoy an excellent economy such as the United States, China, Canada and Russia while others suffer from scarcity, poverty, misery and inflation as most countries of the African continent.The United States is one of the greatest powers in the world while the African countries have fallen is poverty not only for lack of resources but also for disorganization.

     Agriculture is the main sector of activity in Africa, so this area is torn between two models: the traditional subsistence and the plantation model. The ownership of plantations has changed hands after independence. This forces us to assume the risks of a failure to obtain the product. Another important resources  is the animal breeding even though outside of the Savannah, there are not many  pastures;ultimately, mining, and fishing are two very powerful activities, but these two areas are exploited by foreign companies. Knowing all this, the countries of Africa have all the possibilities to become one of the strongest powers in the world; but,  the lack of governmental organization which is the opposite in the United States.

   On the other hand, the United States is the third largest country in the world both in total area and in population. In addition, it has the largest national economy in the world, with an estimated gross domestic product (GDP) of 16.62 billion in 2012, which represents approximately 25 percent of global nominal GDP. It has a mixed economy and has maintained a stable pace of global GDP growth, a moderate unemployment rate, and high levels of research and capital investment.Its five most important trading partners are Canada, China, Mexico, Japan and Germany. The United States has a lot of natural resources. In addition to having the largest global reserves of coal, 22.6 percent of the world total, it also ranks 14th among the largest oil reserves and sixth among the largest reserves of natural gas. Other natural resources that are abundant in the country include lead, copper, phosphates, gold, iron, mercury, silver, nickel, molybdenum, uranium, bauxite, tungsten, potassium, zinc, and wood. Having a good organization this country have an excellent economy.

   In conclusion the African continent has great natural resources that would allow them to become a great power if they had a government capable of correctly managing these resources, which is clearly contrary if we talk about the American economy which is an example since they have protected their resources; in order to prevent foreign companies from dominating them. The United States and Africa are completely different in all economic aspects
