According to the UN Universal Declaration of Human Rights proclaimed by the United Nations General Assembly in Paris on 10 December 1948 (General Assembly resolution 217 A) Article 26.
(1) Everyone has the right to education. Education shall be free, at least in the elementary and fundamental stages. Elementary education shall be compulsory. Technical and professional education shall be made generally available and higher education shall be equally accessible to all on the basis of merit.
(2) Education shall be directed to the full development of the human personality and to the strengthening of respect for human rights and fundamental freedoms. It shall promote understanding, tolerance and friendship among all nations, racial or religious groups, and shall further the activities of the United Nations for the maintenance of peace.
(3) Parents have a prior right to choose the kind of education that shall be given to their children.
Education should be a right because everyone deserves to learn and if kids and people get good educations they can get a good job and make money to support their family and start a family. Education should be everyone, not just the rich not just the white or straight people and should be available for all kids enerywhere
Education is not a right. Public schools are free because states and districts have come together as taxpayers and voted to do so, and they are free to do so. They second you declare something a "right" though, it means the United States military will defend your ability to have those things. Things like free speech, being able to own a gun, not having the police searching your stuff for no good reason, these are all rights. You do NOT have a right to education. People can sell you an education if you would like.
