Group dominance requires relative advantage, not absolute wealth.

Evidence

In order for some groups in society to dominate others, they must have disproportionate access to valued resources. It is not sufficient for them to have a great deal in an absolute sense; they must have more than others in a relative sense. As a result, in societies in which group dominance is evident, there is likely to be a perception that there are not enough valued resources to go around, fueling the belief that groups are chronically competing for valued and scarce resources. — John F. Dovidio, Peter Glick, Laurie A. Rudman, On the Nature of Prejudice, 1501
