Children are the future of a nation, ethnic groupChildren are the asset of futureyou are better to choose one " future of a nation or ethnic group . Therefore, you can change with " As such or for this reason" they need well education and well prepared from a young agedo you mean "childhood"byfor or with good study and good moral development. However, there are so many children have to work at a young age, an age that supposed to be learning and playing. I strongly believe that students as young as fourteen should not be allowed to hold job.While, some children may work in young age that supposed as learning and playing, i firmly believe that "Students or young people as the subject?" should not be allowed to hold a job.
There are now many different mixed opinions on this issueIn conclusion, although a great number of variant perspective happen to this issues, students also can work as an education way. . Some people said that students should have work to do . However, I firmly believe that students should not be permitted to work because it is not their duties at the age of teens, it is too not safe for them to workif you want to make conclusion, it will better giving suggestion of fear to stakeholder or societies .
