I have a friend who's a few years younger than me, and he was a coworker with me at a previous job. He was fresh out of his masters and this was his first job out of school. We became friends fairly quickly, and during lunch one day I mentioned the above "business transaction" stuff, and mentioning that corporations are not your family. It's fine if you like your job, that's a good thing, but just keep in mind that love you show the job will not be reciprocated. He thought I was being extremely cynical (and I suppose I kind of was) and he disagreed with me. About a year later, he felt screwed over by the company, and admitted that maybe I was right. I mentioned it is just a conclusion that nearly anyone comes to when working for the corporate world long enough.
