What group of people has more power than usually in an oligarchy?

In an oligarchy, a small group of individuals holds power, often based on wealth, social status, or military control. Typically, the elite class, including wealthy business leaders or influential political figures, exercises greater power than other segments of society. This concentration of power can marginalize the majority, limiting their influence in governance and decision-making processes. Consequently, the interests of this elite group often dominate the political landscape.
