Functions of social conflict

There are social conflicts to let everybody know that we are created by God unique. When social conflicts are solve it became an avenue for unity.

In reality we are all created equal in Gods image (according to religion) so at what point is it decided by certain people in society that we become unequal and that we all do not have the same rights to all things such as health care, education and even fair and suitable housing ? And why is it that these certain people are most commonly people who feel that their wealth or power within society make them more qualified to sit above all and determine other peoples social status ?
