Walter Reuther, the pioneer UAW organizer, told the story of a conversation with a Ford executive who was showing Reuther his new factory robots. “How are you going to collect union dues from all these machines?” he asked. Reuther said he replied, “You know, that is not what’s bothering me. I’m troubled by the problem of how to sell automobiles to them.” The question of who will have the money to buy tomorrow’s products in an increasingly automated world should be central to every entrepreneur’s thinking.
