Nationalized industries can be prone to interference from politicians for political or populist reasons. Such as, for example, making an industry buy supplies from local producers, when that may be more expensive than buying from abroad, forcing an industry to freeze its prices/fares to satisfy the electorate or control inflation, increasing its staffing to reduce unemployment, or moving its operations to marginal constituencies; it is argued that such measures can cause nationalized industries to become uneconomic and uncompetitive.
