Some background first. If you don't know who George Lakoff is, you probably will soon, if you follow politics. He's a linguistics professor at UC Berkeley and has written extensively on how republicans have used language to successfully frame public discourse in this country, which he calls, conveniently, "framing." Lakoff himself gives us an example:
On the day that George W. Bush took office, the words tax relief started appearing in White House communiqués to the press and in official speeches and reports by conservatives. Let us look in detail at the framing evoked by this term.
The word relief evokes a frame in which there is a blameless Afflicted Person who we identify with and who has some Affliction, some pain or harm that is imposed by some external Cause-of-pain. Relief is the taking away of the pain or harm, and it is brought about by some Reliever-of-pain.
The Relief frame is an instance of a more general Rescue scenario, in which there a Hero (The Reliever-of-pain), a Victim (the Afflicted), a Crime (the Affliction), A Villain (the Cause-of-affliction), and a Rescue (the Pain Relief). The Hero is inherently good, the Villain is evil, and the Victim after the Rescue owes gratitude to the Hero.
The term tax relief evokes all of this and more. Taxes, in this phrase, are the Affliction (the Crime), proponents of taxes are the Causes-of Affliction (the Villains), the taxpayer is the Afflicted Victim, and the proponents of "tax relief" are the Heroes who deserve the taxpayers' gratitude.
Every time the phrase tax relief is used and heard or read by millions of people, the more this view of taxation as an affliction and conservatives as heroes gets reinforced.
