In theory, a market economy with many producers will most efficiently provide products. The reason for this, is that a market economy is ruled by consumers' needs and wants (as opposed to what the government thinks should be) and producers will compete to satisfy these market's needs.
A social contract is an agreement between <u>the ruled and their rulers or the government and the people.</u>
In political philosophy the concept of the social contract was first fully developed by the English philosopher Thomas Hobbes in his book named "Leviathan: The Matter, Form, and Power of a Commonwealth, Ecclesiastical and Civil" (1651).
The author defined a social contract as an agreement between the ruled and their rulers, in which all individuals in a society cede their natural rights (life, liberty, property, etc.) to an absolute government, even meaning that individuals would have to accept abuses of power. Through the contract people could live better and maintain peace, receive protection and avoid conflict by the establishment of a civil society.
