Upper class
Upper class is an idea in sociology. It refers to the group of people at the top of a society. They are the wealthiest group of society. Members of an upper class often have great power over resources and governmental policy in their area. They may have acquired these things by inheritance, for example by being monarchs or aristocrats, or by commerce. They may own much land or other valuable property, and may spend much of their income on luxury goods such as yachts and mansions.
