Groups of people or communities may have the experience of being excluded. Their marginalization can be because they speak a different language, follow different customs or belong to a different religious group from the majority community. They may also feel marginalized because they are poor, considered to be of low social status and viewed as being less human than others. The government releases various schemes to gain profit through the influence of these people and groups.
