What sense would it make to classify a man as handicapped because he is in a wheelchair today, if he is expected to be walking again in a month, and competing in track meets before the year is out? Yet Americans are generally given 'class' labels on the basis of their transient location in the income stream. If most Americans do not stay in the same broad income bracket for even a decade, their repeatedly changing 'class' makes class itself a nebulous concept. Yet the intelligentsia are habituated, if not addicted, to seeing the world in class terms.
The staunchest conservatives advocate a range of changes which differ in specifics, rather than in number or magnitude, from the changes advocated by those considered liberalchange, as such, is simply not a controversial issue. Yet a common practice among the anointed is to declare themselves emphatically, piously, and defiantly in favor of 'change.' Thus those who oppose their particular changes are depicted as being against change in general. It is as if opponents of the equation 2 2=7 were depicted as being against mathematics. Such a tactic might, however, be more politically effective than trying to defend the equation on its own merits.
