And what exactly was the purpose he served?
When a man buys several companies then merges them he has a lot of surplus upper management people that are not “deserving” of getting fired and are not about to resign. Firing them would cause strife and stress among those officers to be retained. The owner hires a professional transition manager to amalgamate the companies who then makes it uncomfortable for the fellows who need to be removed so that they quit, sometimes in a loud and angry huff but the remainers are not disturbed. The contract with the outside transition manager then lapses and he is then “fired” indignantly to retain the illusion that the new Owner is not “at fault” for the superfluous officers losing their jobs. Such pros are ultra abrasive which is their desirable talent. They don’t have to be in political or process agreement with the one who hired them. Scaramucci served that purpose and DJT expressed faux regret that certain employees chose to resign. Scaramucci is of such character and note that all his “insider” tell-alling is harmless pitter patter. He was the right man for the job. He has served that same purpose before in the business world and had a certain reputation for his effectiveness.
