There are typically minority and majority powers which have to be recognized. This typically is correlated with the prevalence of a particular ethnic group acting in its own interests by numerical representation, but it does not always exist this way. In some places it is easy to see how current minority groups becoming majority groups would still not inherit power accumulated via generational wealth, or would not have a realistic means of gaining consensus on changing socioeconomic circumstances in their favor.
A more collaborative approach to different groups in a system would be necessary, instead of fearing demographic changes.
