Yet another reason is the economic clout generated by this class. In 2005 according to U.S. Census statistics, the top third of society, excluding the top 5%, controlled the largest share of income in the United States. Although some in the statistical middle class (for example, police officers and fire fighters in the more affluent suburbs in the San Francisco Bay Area) may have lifestyles as comfortable as those found among the ranks of the professional middle class, only few have the same degree of autonomy and influence over society as those in the professional middle class. Other white-collar members of the statistical middle class may not only be unable to afford the middle-class lifestyle but also lack the influence found in the professional middle class.
