What do humans lose and gain by the social contract?

What people lose in the social contract is a few freedoms, but they gain a whole new aspect that makes up for their loss. They receive a perfect union among the community, in which all people are equals, including the government. Jean-Jacquw Rousseau explains that the association would become tyrannical if the state of nature is tampered with.(The state of nature being the way that people act naturally, without government interference.) In the end, though, people gain the sum of forces by placing all power in to a common general, who maintains everyone's mutual benefit in the community. By allowing this to happen, an invisible and equal part of the whole is redistributed. People's morality is what helps create an even greater amount of force preservation, and everyone in this perfect society potentially earns more than the force they put in by responding in a moral behavior.
