Sometimes those in a leadership loose focus of this and their main concern is the "business model".
A leaders responsibility is to maintain the businesses success... and manage, in a thoughtful manner, those under their charge. This means making sure that their goals and aspirations are being met.
Your success is dependent upon the quality of those around you and you will only be able to retain quality people by keeping them engaged, active in leadership decisions (direction) and providing them with opportunities to grow. I think this is crucial than ever before as this is the evolution of good business management.
And remember, you are a leader, regardless of your position.
