Pork barrel
Pork barrel is a derogatory term used to describe government spending that is intended to enrich constituents of a politician in return for their political support, either in the form of campaign contributions or votes. Typically it involves funding for government programs whose economic or service benefits are concentrated but whose costs are spread among all taxpayers. Public works projects and agricultural subsidies are the most commonly cited examples, but do not exhaust the possibilities. Pork barreling is an important explanation for government deficits.One of the earliest examples of pork barreling was the Bonus Bill of 1817, which was introduced by John Calhoun to construct highways linking the East and South of the United States to its Western frontier using the earnings Bonus from the Second Bank of the United States. Calhoun argued for it using general welfare and post roads clauses of the United States Constitution. Although he approved of the economic development goal, President James Madison vetoed the bill as unconstitutional. Since then however, U.S. presidents have seen the political advantage of pork barreling.
