In Hollywood, celebrity success always comes with hefty paychecks. Every movie feature, brand sponsorship, and television appearance can easily top an average person's yearly salary. However, not all celebrities want to keep their money all to themselves. Whilst some choose to flaunt their luxurious lifestyles, other celebrities choose to devote their time and resources to help advance the welfare of others, to help make a positive impact on their community. Angelina Jolie has been working on refugee missions since 2001 and has since been appointed Special Convoy to the United Nations High Commissioner for Refugees. She has carried out nearly 60 field missions through this role and even created the Jolie-Pitt Foundation with her ex- husband in an effort to aid humanitarian causes across the world. Jolie particularly champions the significance of women's rights, serving as a visiting speaker at the London School of Economics on this topic as well as founding schools for girls in Kenya and eastern Afghanistan.
