Work Culture in an Organization

Recently I read about a person returning to an organization inspite of having more lucrative offers because he missed the work culture. This brings forth a thought whether people work for money or they like to work where they cherish a nice friendly atomsphere.
I have changed jobs twice , first time it was for couple of reasons - money being one of them, peer pressure being another and some more. Second time was due to organization closing down , so it is difficult for me to comment

Though there have been theories that people dont leave organizations , they leave managers. I feel this is quite true because finally it is the manager only who can develop and nurture a culture in his group
