Bad vibes?
I suspect you have gotten more than one raw deal from a corporation in the past. It kind of leaks out the seams of your posts. Kind of like the anger towards the higher education system that oozed from between the lines (and the lines themselves sometimes) in Success Machine's posts. There was obviously a history there.
There are corporations and corporations. I have worked for them before, just not for many years. I worked for 3M, which was exemplary about rewarding the efforts of its inventors. Maybe that was an odd outfit compared to others, and I don't have others to compare it with (a short stint at IBM as a temp).
