Between 1965 and 1974, the Appalachian Regional Commission (ARC) spent in excess of $2 billion. Since 1974, that figure has climbed to more than $4 billion, with the bulk of these funds spent for road building and vocational schools. Despite this outpouring of funds, many in the region have never heard of the ARC. Part of the problem is ARC's lack of credibility, caused by less than spectacular results.
