In agreement with the above posts, I'd say: By accepting a certain value-based view of society as fundamental or "real", people can lose sight of the potential for challenging that view, changing the values that go into that view, or alterting situations of inequality that are accepted in the value-based view.
If you feel that things are as they should be because one perspective says so, you may not believe that change is possible. If you are a minority in a society where the dominant view of you is negative and limited, you may view your potential negatively and within limits that are not real, only perceived and part of in the dominant paradigm.
I agree with Post 3 more than with Post 2. We are socialized to believe that inequality is the natural way of the world. Because we are socialized in this way, we do not question it. We just accept that some people should be treated as inferiors and that perpetuates inequality.
Race and gender are immutable characteristics, so if we are socialized to find one race or gender to be inferior, which many people in many societies have been, it is extremely difficult to transcend that socialization, for the people who hold those opinions and for their victims, who, of course, cannot change at all. Changing laws is not enough to completely overcome the socialization of inequality.
One of the ways socialization contributes to continued inequalities is that people have the values and habits they were raised with. If they are raised in a culture of poverty, it is very hard to overcome that. Not only are you socialized in ways society does not value, you do not have the socialization that society does value.
