Provide an evaluation of access to free basic education showing both advantages and disadvantages

Access to free basic education is a basic human right as all children need to be educated to be able to survive in our world and many kids can't go to school because they must scrounge for the basic necessities of life to help their parents who don't have work and live in squalor in various parts of the world. But calling it free is not quite right as it's expenses must be paid from our taxes so we are still paying for it. On the other hand, there are those well to do people who can pay for private education so may get a better quality of education and/or those who are not rich may still have private school education for those individuals who need special attention like those with a learning disability but such things should be fought for for the public education system.
