Michael Betrays his Catherine Zeta

I am still disgusted by last night's episode, "The Deposition", where Michael sabotages Jan's chance to get $4 million dollars from Dunder Mifflin out of loyalty for a company that promoted his inexperienced "mento" (Tracy Jordan, 30 Rock), Ryan, instead of him. A previous episode revealed that Michael was severely underpaid, especially since he was responsible for overseeing the merging of the Scranton and Stamford branch offices. David, the CFO, confirmed the fact that Michael was able to cut costs without losing a single customer. However, Michael did not get promoted. Ryan did. It sounds like David should be getting a poor performance review.
