Employees have always been responsible for managing their own career growth and always will be. How can it be otherwise? It would be foolish for an employee to let someone else handle career growth for them as their interests aren't aligned (or even known). If you want help with career growth then find a mentor, don't rely on your manager.
Managers should facilitate training to improve employee productivity and help prepare them for a promotion. But that isn't really the same as career growth.
