A successful country, the definition of which though does not gain a consensus, means more than just one factor. (定语从句，插入语)
Economy is widely recognized as a crucial criterion to judge a nation because it is a sound economic development that determines the living standard and that provides financial resources to other domains of a society including education, scientific research and public health. In addition, there is a close association between wealth and low crime rate. (被动句，原因状语从句，强调句，非谓语)
However, economic status is not the only consideration in the judgment of a nation and there are a variety of other elements to define an ideal society. A healthy natural environment would make sure that our next generation can keep living on the earth. Healthy lifestyles make healthy and happy workers who are able to make contribution to his/her community. In addition, dynamic and characteristic culture and democraticpolitics is universally desirable and is seen as a symbol of progress and civilization. (并列句，there be 句型，定语从句，宾语从句)
Among these factors, I believe that education is the fundamental one to judge whether a country is successful or not. The major reason is that education determines whether a country can succeed economically in a sustainable way. Without education of high quality, there would be deficient labour force of high quality to ensure a long termeconomic boom which in modern high-tech and information society requires much morewell-educated professionals with the spirit of innovation and creation than in the industrial society. Education also makes incredible contribution to other importantsectors. It helps lower the crime rate and increase public awareness to the environment, health and politics.
