Basics forgotten or ignored ???

Planning Organizing Directing Controlling are the basic four functions of management.
When the management talks about all these basics then how come the so called management cannot keep the business running smoothly. Are all these management concepts only in books ??? Or have they forgotten to follow the basics or ignored ?

Management highly talk about Vision.Is this also just another fancy statement ??? If all work towards Vision then how come organizations facing problems ??
Is it a problem with the Vision or the people who create the Vision. Then have to ask a simple question. Who create ?? which level of the organizational structure ? So from where all these problems arise ??? Who create all these problems ???
