You see the same thing here in the U.S., and to be honest, I think it's somewhat accurate. The vast majority of the United States is middle class, and there is a huge range of privilege within it. Some parts of the middle class are virtually inaccessible from other parts. The mistake is not in labeling those rich, privileged people "middle class," but rather in thinking that there is no such thing as middle class privilege. In fact, being born into the middle class is a privilege, and there is a vast range of privilege within the middle class. In the U.S. a middle class kid could have parents with high school diplomas or parents with PhDs, parents with no connections or parents with Ivy League connections, parents who have never been more than a few hundred miles from home or cosmopolitan globe-hopping parents, parents who force them to take out loans for college or parents who pay the entire cost of an Ivy League education with a break year plus professional school afterwards and apartments and cars the whole time. The label "middle class" just doesn't mean much these days.
