Members of privileged groups have important roles to play in social justice efforts. Because they have social advantages and greater access to resources, they are in unique positions to address issues in ways that are more difficult for those with disadvantages, as they are somewhat protected from the negative outcomes of doing so.

This chapter highlights how the participation of those in privileged groups is essential to the success of social movements.
