What's Good for Big Business Not Necessarily Good for National Economy, New Study Finds
FAYETTEVILLE, Ark. – In 1953, during a Senate Armed Services Committee hearing to determine whether he would become U.S. secretary of defense, Charles E. Wilson famously stated that keeping his existing job as head of General Motors would not constitute a conflict of interest because “what was good for our country was good for General Motors, and vice versa.” A new study by a University of Arkansas researcher suggests the opposite – that a stable group of large corporations is associated with slower economic growth, particularly in high-income countries. |
