The correct answer to this open question is the following.
Although you did not attach any text, article, or lecture to provide specific evidence, we can comment on the following so you can get some good ideas for your essay.
"The desire for fairness drives conflict and ultimately, change."
What is fair for you could not be fair for me.
One of the constant conflicts between humans is trying to apply our values and definitions of what is right to other people.
And that is wneh trouble starts. What can be good for you could not be god for me or your neighborhood.
So the desire for fairness depends on your set of values education and belief systems. However, when we include the reasons for fairness that benefits the majority, then people can understand the benefits of living in harmony, peace, respect, and tolerance, although you have to refrain from something you like or consider good.
As the moral value it is, fairness can be interpreted according to people's interests. Nonetheless, everything that is thought to be in equity and harmony for everybody requires changes and adaptations. This means that to live in harmony and in peace, you sometimes -and of course, other people too- have to concede something. That is a decent way to get to an understanding of the conditions that benefit the majority.
New social conditions require new ways to confront and resolve issues that benefit the majority of people.
