Wow that's fairly insulting and not really an appropriate comparison at all. Peter Keating was anything but an arrogant egoist, and he bent over backwards to please the people he dealt with (his superiors at least)
Tell me that using the dealer trick to not have a license plate is somehow not the same childish level of vanity that you would expect of a successful manchild.
A non-exhaustive list of things which the law allows for and which many people have the ability to do:
* Call you names * Give you projects that are doomed to fail * Place you on a team which will drag you down * Use you as a scapegoat for the failure of a project * Use KLOC as a metric of performance * Show you the finger at a traffic light
And yet we don't approve of these things. Something being lawful is the bare minimum, not the gold standard.
