Last week, President Obama went on the road promoting an economic agenda for the middle class. As expected, John Boehner and other Republicans fired back by charging Obama with “squeezing the middle class.” It’s not even an election year, yet “middle class” is hotly contested linguistic real estate. But nobody seems to know what this term means.
“Middle class” remains our favored self-designation, although the percentage of Americans who select it fell from 53 percent in 2008 to 49 most recently, according to Pew Research. As a friend’s high-school teacher loved to say, “The great thing about America is that everyone can be middle class.” Good thing she wasn’t teaching math.

Given this popularity, it is no mystery why “in the interest of the middle class” now beats “for the children” as political cliché. The puzzle is why so many who do not fit the category (as median family income reported as just above $50,000 defines it) believe they do. Why does the description “middle-class nation” continue to feel appropriate, desirable, or both?
Researching how people’s unconscious assumptions affect their perception of economic issues, I explored the linguistic dynamics behind the term “middle class,” especially in comparison to other economic groupings. In the Corpus of Contemporary American English, a database of more than 450 million words from speeches, media, fiction, and academic texts, among the most common words (excluding conjunctions and prepositions among others) co-occurring with “middle class” we find “emerging,” “burgeoning,” “burdened,” and “squeezed.” These tell us what happens to this grouping. Absent are quantitative terms or descriptors for what life is like within this category. In fact, in common usage, we rarely hear about actual people named within it; middle class may as well describe a grouping of potted plants or pop cans. There’s little here tied to income or lifestyle.
