There are several reasons for people to stay at school until they are 18: but the most significant explaination is about the protection of school. This is because if people are under 18, they are still not mature enough and can be easily fall into social evils such as: addiction, scrimmage or pre-age sex.Educational insitution, because of these problems, are responsible for teaching students to stay away from them and leaners will then have a full awareness of various social evils in life.
It is also something suggested that people choosing to study until 18 will have a better opportunity to land a good job.This is because degree, which is a recognition of a study process is often considered as a compulsory factor of every company, especial with the good reputation one.One illustration of this is that the ratio for a man who does not study at least 12 years, wants to work for a company is very low (5%-15%) because he does not even response to one the most basic need of every company.In contrast, the one who study until 18 or even higher is often be appriciated and can get a good job easily.
