Should education be free for students??

This policy has both advantages and disadvantages. 
On one hand, by following this policy, governments have the highest skilled labor with all citizens being well educated. Besides, education should be the equal right for all people. Poor but good learning kids still can go to school like others.
However, there are some drawbacks. Governments may lack funding to develop other key industries. In addition, educators hardly have enough money to pay for teachers and upgrade facilities. Besides, by paying, students take knowledge seriously and see education as a valuable service. In most famous schools around the world, students are supposed to be responsible for this service like Havard and Yale university.
