I think it should be the goal of every organization that the next hire always be better than the last. They should get there by making sure that they train and build up every previous hire to be better than they were and making their teams be attractive to higher caliber recruits. A business really doing well should elevate all the employees - wages, skills, lifestyle - and that is what lets them hire well. But boy is it hard to communicate that scheme in two sentences at an all-hands pep talk.
