A proposal to turn over Pennsylvania's state-controlled sale of liquor and wine to private business would drive up prices, limit the selection of products and leave many rural residents without a nearby liquor store, critics warned lawmakers Thursday. Joe Conti, chief executive officer of the Pennsylvania Liquor Control Board, and Wendell Young IV, president of the union that represents most state-store workers, said changes the board has implemented in the 620 state stores in recent years have made prices more competitive, expanded the selection and enhanced convenience.
