Crud

So the job I wanted was swooped up by someone else and it's is no one's fault except mine. I could have gotten that job months ago but I decided to stay where I am at the time because I was still infatuated with the idea of fixing things here, which is obviously not going to happen. At least not any time soon.
What I don't understand is why is it wrong to try to make things better? I understand that there is change management etc, but our piece of crap software needs help and it needs it badly. I am tired of begging to make things better or to even make it all work.
I hate this place because of this and all because of one man.
Either way I think I am out the door.
