Marvin Miller transformed the Major League Baseball Players Association in the nineteen-seventies. Miller, a former labor negotiator for the United Steelworkers, would talk to the players about how unfair their contracts were and how much better things would be if they organized themselves. Visiting the San Francisco Giants at spring training one year, Miller predicted that if they could get rid of the system as they knew it then, the son of Giants right fielder Bobby Bonds would, if he made it to the major leagues, earn more in one year than Bobby earned in his career. Bobby Bonds’s son, Barry, ended up making more in one year than all of his father’s team made in their entire careers, combined.
