Against

1. Education may give one a job but having a job does not guarantee anyone success in life.
2. In order to be successful, one has to know how to manage money, people and people's problems and diploma education hardly teaches us that.
3. Diploma education without any marketable skill is a waste of time and resources.
4. People get successful because they solve other people's problems and get paid for such not because they have possessed diploma education.
5. Most successful people in the world today don't have formal diploma education and the have many diploma holders working for them for peanuts.
6. Diploma education only teaches people how to be employees. It hardly teaches people how to generate wealth.
7. Being successful in life has nothing to do with education. Anyone can be successful in life if they know what they want and pursue it with all their hearts.

Education is good but it doesn't guarantee success. Some of the most frustrated people in life are people that thought that education is all they need to become successful in life and invested everything they have in it only for them to discover that it takes much more than just acquiring education to be successful.
