Behind the scenes
In reality, "" is a term for a forced choice between two lines of reasoning which lead to the same unpleasant conclusion. It derives from, Archbishop of Canterbury and Lord Chancellor under Henry VII, who argued that a man living frugally must have money to spare and therefore could afford to pay taxes, and that a man living opulently must be rich and therefore could afford to pay taxes.
