Grandiosity refers to an unrealistic sense of superiority—a sustained view of oneself as better than others that causes the narcissist to view others with disdain or as inferior—as well as to a sense of uniqueness: the belief that few others have anything in common with oneself and that one can only be understood by a few or very special people.
Let's see how well he fits the established warning signs of oblivious narcissism:
- "Observed lack of insight into the impact they have on others." He never seems to understand what he's doing to piss people off. From not understanding that Elly wasn't put on this Earth to clean up after him to not realizing that most of what's wrong with Liz is that she has an instinctive dread of a looming shape of imbecile malice with dirty black hair, Mike doesn't see himself as being the huge God-damned pain in the neck they'll be cremating fifty years from now.
- "More likely to regulate self-esteem through overt self-enhancement." Mike never seems to shut up about the good things that happen to him because he sees himself as reminding people of how worth it hanging on every stupid word he says is.
- "Denial of weaknesses." He never seems to admit that he isn't very smart and doesn't really understand people at all well. What's more, he doesn't seem to understand how flawed his reasoning is.
- "Intimidating demands of entitlement." The irritating situation he'd gotten into when Martha's friends said that she had to share everything with them or they'd turn on her in a Milborough minute seems to fit the bill for that. She had the choice of not getting eaten alive or being worthy in the eyes of an entitled jerk.
- "Consistent anger in unmet expectations." There are too many examples of Mike losing his shit when he can't get his own way to list.
- "Devaluation of people that threaten self-esteem." Sistwirp. Lizardbreath. Res ipsa loquitur.
- "Diminished awareness of the dissonance between their expectations and reality, along with the impact this has on relationships." The best example of this is, I should think, his stupid comment about being a bug on Rhetta's windshield the second she said she has emotional needs because it was clear to his dumb ass that she should have been content to sit on her hands and wait for him like a passive twit. A normal person would have been upset by her friend-zoning him but not squealed about having his heart crushed in a machine.
- "Overt presentation of grandiose fantasies." We have any number of letters that have the deluded clod think that his terrible books are the reason alphabetic literacy was invented as proof; to hear him talk, you'd think he licked the Kaiser.
- "Conflict within the environment is generally experienced as external to these individuals and not a measure of their own unrealistic expectations." The Stalinist purge inflicted on Divala because he confused being asked to pay his dues like everyone else with being a rung on a ladder is the best example of this. The second best is assuming that it's something about Liz that makes him want to crush her because the alternative is touching off the depressive phase of his narcissism in which he makes a pain of himself yapping about what a worthless scumbag he is.
Simply put, Michael has always believed that he deserves all the attention and cannot quite cope with the idea that other people need not to have the son shine in their faces all the time. The only real cure I can think of for his mania is the total implosion of his personality when it becomes too hard to maintain the grand facade. Narcissistic idiots like him have a way of crashing and burning leaving wreckage in their wake. His will be a wife having to go back to behind a pharmacy counter when the executor of someone's estate comes after him for pillaging the person's past in order to create a horrible book. When that happens, he might make a sloppy attempt at suicide in order to make one last grab for attention.
