A free enterprise economy or system is the same as a market economy. A public official is a person holding a post to which he or she has been legally elected or appointed who performs governmental functions. A policeman, mayor, and justice of the peace are public officials. To have citizenship is to be an official member of a politically defined region. A citizen owes allegiance to his or her country and expects to be protected by the government and from unfair use of governmental power.
Students can be citizens of their classroom entitled to protection by their student government.
Citizens can be natural born or naturalized. In most cases, when naturalized, they vow their allegiance to their adopted country and cease being legal citizens of their homeland. A symbol is something which stands for or suggests something else. It can be a visible sign of something which is intangible. The Statue of Liberty, for example, is a symbol of freedom.
