Why Do We Go To School/ What Do The Kids Learn In School

WHAT DO THE KIDS LEARN IN SCHOOL? is a popular verse from Will Smiths version of just the two of us. it is a pity that we have so many schools in the country today,but many are without aims and objectives. many students go to school today. but ask many why they are in the higher institutions to learn, they will tell you that they want to have cert. so taht they can get a good job. Going back in history to the time of Aristole and other Greeks philosophers down to Alexander the Great who establish the first university why they did that, i dont think we will have the same anwser with that of many nigerian students. If our motive for going to school is to make money,Bill Gate who is the the richest man dropped out from school. WHY?
  Bill happens to be the backbone of many current computer software break through, yet because he had not receive the formal lectures taugth in school, how come he achived what he did and many university turnovers are trying to caugth up. Then the question WHAT DOES THE KIDS LEARN IN SCHOOL.
   It is not strange that when one under go an improper conducts, many illitrates will say ' but he/she is educated'. is decency part of what one must learn in school?
many of our computer grad. are refferred to as been unemployable. they are asked to go for certifications in niit,,  then why all these years in school.  why then do i not jsut go for the certification and get on with life. many people see you as a dropout, this that when youve not enrolled and grad in one field or the other. why must i go to school. cant i just get books, read and take exams as we have for the visionaries of those who started the open universities. many people are now enrolling in the ipods university where you just download lectures/  materials read and digest and you get on well with life. no exams, no cert. just read and be digest. is this not the aims of education, understanding things. then why must i then go to school?
