As socio–psychologists describe, Human beings identify themselves as part of their group. They felt prestigious and energetic only when they are recognized as a part of their own group.
What discrimination means is that out-grouping their own members from the membership of their group or banning their members from accessing natural resources. Indeed, wealth is an important matter.
Someone of the group’s eligibility and self–respect indirectly defends someone getting wealth. Empirical studies confirm that persons with a low sense of social recognition display more out-group devaluation and group-focused enmity based on an ideology of human inequality.
Negative attitudes toward different out-groups (ethnic and religious minorities, women, and people who are disabled or homeless) are strongly correlated with each other, indicating the unspecific nature of discrimination.
