From Pillar to Post

For the past nine months I have been trying to move to this division in my org - well i have finally made it here , but they d made me run around for this a loooong time ...
Makes me wonder ... are people just not competent enuff to do their work or are they cruelly sadistic when it comes to exerting their power to stop others from going where they wanna go? what is it that makes people who manage other people tick?
where does personal ego end and professional power play come into effect?
and does professionalism exist at all? and most importantly, where does personal competition fit into all of this?
Why are we complicating things this way?
Why am I asking so many questions? Where are the answers?
