The correct answer is the following.
Jean-Jaques Rousseau said that property was the most sacred of all rights of citizenship because people need to have their own things to prosper in a society. Rosseau considered that private property protection was the most important function of a government. These Rousseau's ideas are included in his book called "The Social Contract" in 1762, that follows his book "Discourse on Inequality" of 1754. Rosseau referred to the kind of government that could help people to resolve their economic issues.
