A student comes into a professor's office to ask for help. What's going to happen to the student if he starts acting like he's got higher status than the professor? Nothing good.
Likewise, if I start lording myself over my friends (who are supposed to be my equals) then they're gonna stop being my friends pretty soon.
The number of social situations in which artificially attempting to raise your status is a good idea is pretty limited. The only really useful part of all this is in making sure you don't give off an artificially low status.
