“epitome of an executive”??? OMG, Trump would wouldn’t last 6 months until the board of directors of a major corp. would show him the door.
Why do you believe that? His lack of political correctness?
Most major corporations are poorly run and depend on competitive restrictions such as regulation or economies of scale to persist. They are almost pathologically unenterprising. Most would not tolerate a true entrepreneur as CEO.
The model of this is when Apple, back when it was saddled with highly qualified professional management at the behest of the major investors, threw out Steve Jobs.
