You do not think that consistently hiring unqualified people, or people who fail, is a problem? I'm not sure why you'd want to normalize such a thing; and to be clear, it's not normal to have this much turnover this quickly.Yes he has had problems with his staff, so what. Judgement in hiring them? A position has to be filled, you hire someone that appears to have what it takes to do the job then you find out you are wrong and you replace them. So what's the problem?
What happened to Trump's promise to hire the "best people" for his administration? Trump was warned by multiple people that Flynn was compromised and should not be trusted with sensitive material; he was hired anyway. Scaramouche had zero communications experience; he was hired as communications director. These aren't the "best people" who, through unforeseen misfortune, just ended up not working out; these were known problems from the get-go.
Basically, the only experience Trump brought to the White House was as a manager. The staff turnover, and poor staff picks in the first place, are evidence of poor management. Why do you excuse this?
