Public policy is a phrase that refers to a government policy which affects the public and the population. You will find public policy quotes about poverty, education, and many other topics that affect ordinary people of all income levels. Public policy can have a positive or negative effect on the citizens of a country, depending on the policy that is involved. A government may enact public policy about any pressing need that citizens face, and this includes passing or creating new laws that address the issues under consideration. In the United States it is illegal to purchase or sell body parts, or to sell your body for sexual favors except in specific areas where prostitution is legal, as a matter of public policy and to protect the public from harms that could occur as a result of these activities.
