Democracy has a number of advantages, foremost among which are safeguarding and representing the interests of the people. Equality is also key to democracy, and this includes equality before the law and equal rights to power.
Equality before the law essentially means that no person should be discriminated against because of their race, wealth or connections. Similarly, these factors should not prevent any person from being elected as an official representative of the people.
Democracy also seeks to safeguard freedom. As a political doctrine, it accepts the need for a government but states that it is the job of the government to promote peace and unity.
In theory, democracy should be driven by public will, thereby eliminating the need for and likelihood of sedition or revolution. As some have pointed out, however, at the enormous scale of contemporary nations impedes true representation of every person's interests. Each member of the United States House of Representatives, for example, is theoretically responsible for safeguarding the interests of, on average, 710,787 people. For this reason, it would be virtually impossible for all citizens to express their interests to their elected official.
Nevertheless, the principles of democracy in theory remain inherently advantageous to citizens, and democratic governments remain answerable to the people.
