Makes the world a safer and more peaceful place
Education majorly affects our understanding of the difference between right and wrong. An educated person is well aware of the consequences of wrong/illegal actions and he is less likely to get influenced and do something which is not legally/morally right. Also, a number of uneducated people who live a poverty stricken life owning to lack of opportunities often turn to illegal ways such as theft and robbery to solve their problems. If you are educated, you are well aware of your rights, the law and your responsibilities towards the society. Hence, education is an important factor which contributes in social harmony and peace.
Makes you confident
Your educational degree is considered as a proof of your knowledge by many. If you are educated you have more chances of being heard and taken seriously. Generally, an uneducated man will find it harder to express his views and opinions owning to lack of confidence. Even if he does so, people may not take him seriously. Education gives you the confidence to express your views and opinions.
Society
We all live in a society which has its own set spoken/unspoken rules and one of them is education. The society expects you to go to school followed by college, get a job, settle down etc. In fact education helps you become a useful member of the society. An educated member certainly has a greater chance to contribute to his community. Education helps you become an active member of the society and participate in the ongoing changes and developments.
For economic growth of the nation
Australia, USA and Japan are few countries with very high literacy rates. These countries are extremely prosperous and the citizens have a high per capita income. On the other hand, in underdeveloped and developing nations, where literacy rate is not as high, a number of people are still living below the poverty line. Education is vital for the economic prosperity of a nation!
Saves you from being fooled/cheated
Education saves you from being exploited and fooled. We live in a country where we enjoy a number of rights and freedom. It is easier to take advantage of innocent and illiterate people. They may be trapped into signing false documents or be deprived of some right which they have because unlike an educated person they are not well aware of their rights and freedoms.
