Because in the real world it was discovered many years ago that reward outweighs threat. If you intimidate people they do not work well for you and are always looking for greener pastures. If you nurture and reward you keep good people.
I realise as I only have a few thousand people working for me that I have little understanding of the concept but I like to think I understand the basic elements.
