What do you know about the standard of living of a country? It actually means how much of the goods and services the country produces for an average person to share.    1.    Obviously, the first factor is its ability to produce wealth. “Wealth” in this sense doesn’t refer to money. It’s because we don’t live on money but on things that money can buy, “goods” such as food and clothing, and “services” such as transport and entertainment.

   There are various factors that determine a country’s ability to produce wealth. They affect one another. Wealth depends greatly on a country’s natural resources.    2.   . Some regions of the world are rich in natural resources with a fertile soil and a favorable climate; other regions possess perhaps only one of them; some, unfortunately, possess none. The USA has everything listed above.    3.  The Sahara Desert, on the other hand, is one of the least wealthy.

    Also, the ability to put natural resources to use counts, which goes without saying.

      4.  As we see, old countries that have trained so many skilled workers over centimes are better at producing wealth than those whose workers are mainly unskilled.

   Besides, with their wealth increasing, people have more for saving and can put their savings into factories and machines, which, in turn, will help workers to produce more goods.   5.

A. That means wealth itself also produces wealth.

B. No wonder it is one of the wealthiest regions of the world.

C. Natural resources are equally distributed around the world.

D. And next comes the technical efficiency of a country’s people.

E. You may ask what factors contribute to a country’s standard of living

F. They include coal, oil, gas, gold, other minerals, water supply and so on.

G. But that doesn’t make it a most wealthy country because it’s often hit by disasters.
