There's a big difference between managing and leading people. Managers control tangible assets like plant and equipment, inventory and accounts receivable, etc.
Managers also control budgets and enforce company policy.
All these things are important, of course. The best managers are also good coaches who care about people, ideas, innovation, and imagination. They inspire their people and lead by example serving as role models for the entire organization. Good management is a sub-set of good leadership. The finest leaders of today are empowered to act in the best interest of their people and organization.
