How could Rousseau's concept of "general will" be used to eliminate the rights of the minority?

Understanding deeply, Rousseau believed that the man wanted to live in a community, but the necessity to pursue goods and riches corrupted the man. And then, some people begin to have more than others and to control politics. The idea of the general will is based on this small group of people, who will do whatever it takes to maintain their privileges.
