glass-tower people, the professional and managerial members of the U.S. upper middle class, who are college-educated, economically ascendant, and sophisticated to the extent that they understand and encourage change and cultural diversity. Also called the have-mores: "The middle class, long the balance wheel of American society, is beginning to fissure along fault lines of income, values and lifestyle. It is cleaving into the have-mores--'the glass-tower people,' Labor Secretary Robert Reich calls them--and the have-lesses" (Wall Street Journal).
Background: Glass-tower people--a term with obvious links to ivory tower--joins a small but growing lexicon of class conflict. Some established examples are cultural elites and angry white males. Less well known terms include unearned advantage (or unearned privilege), skin-color privilege, and male privilege, expressions used by Peggy McIntosh, a philosopher of education at Wellesley College, to point up the social stratification that race, sex, and class can create.
human bowling, a form of entertainment in which players roll a round steel-mesh cage into which a person has been strapped down a padded runway in an attempt to knock down six heavy, oversized pins at the end: "Alcohol- and drug-free parties have followed proms and graduations for years, but movies and bingo look pretty tame compared to today's gigs that run more than $10,000 in wealthier suburbs. The same boys and girls who once were entertained with birthday party magicians now look forward to bungee runs and Velcro walls, sumo wrestling and human bowling, all between 1 a.m. and 5 a.m." (Washington Post).
