The most prominent academic models split the middle class into two sections. Yet, it remains common for the term middle class to be applied for anyone in between either extreme of the socio-economic strata. The middle class is then often sub-divided into an upper-middle, middle-middle, and lower-middle class. In colloquial descriptions of the class system the middle-middle class may be described as consisting of those in the middle of the social strata. Politicians and television personalities such as Lou Dobbs can be seen using the term middle class in this manner, especially when discussing the middle-class squeeze. The wide discrepancy between the academic models and public opinions that lump highly educated professionals together in the same class with secretaries may lead to the conclusion that public opinion on the subject has become largely ambiguous.
