Education is the single most important factor in the development of
a country? Do you agree?

Every country is making the best efforts to develop and become a strong nation. And one of the firmest foundations in the development of
a country is education. Without education,we wouldn’t have such a beautiful life as now. So that,people should be well-educated to improve not only ourselves but also our country for some reasons.

Firstly, having good education can help us easily access to many things in our life. In class, teachers teach us theories of some subjects,which can give us a great deal of information about many diffirent fields,such as geography,history,mathematics,etc. Thanks to that,we can use the knowlegde we were taught to practice in real life.Furthermore,in fact,if we know the details about something in advance,we can get accustomed to it more easily . For examples,having huge knowledge about mathematics,we can quickly get access to machinery industry which is very popular now.So that,if people in a country were well-educated,they would have good qualifications so as to develop their country’s industry and economy.

Secondly,education teaches us how to live and to behave rightly,which helps reduce violence and promote the development of a country. Nowadays, social violence is quickly increasing,which causes some negative economic and social effects on people who are living in that area.So that,in every schools,teachers always use moral education to teach their students. It’s very nessesary,especially for children. As we know,children will be laborer in future.,so that the more good things they learn,the brighter our life will be. When learing how to behave rightly,people will live together happily and together develop their country.

The last and also the most important thing which education helps us is to reduce a large number of illiterate and social evils. As we know,one of the foundations to develop a country is having less illiterate as much as possible. Without being educated,people will become stupid and their country will be fall behind.Moreover, the illiteracy also causes some bad affects,such as poverty,social evils,etc.,which is extremely dangerous. People knowing nothing can’t distinguish right from wrong,they can do anything to survive. That is why the percentage of theft ,Drug addiction, Gambling is highly increasing now,which delays the development of the country.

Through some above-mentioned reasons,we can see that THE educational factor in developing countries is the single most important factor. It's a firm foundation for most countries, especially developing countries.
