The fact the Donald Trump is ignorant is obvious. The fact that he is arrogant is equally obvious.
Donald Trump is the most arrogant President ever to serve as the President of the United States. Arrogance crosses the line of confidence. Arrogant people, like Trump, believe they no longer have a need to learn, grow, or change. They wholeheartedly believe that they are right and others are wrong. Trump believes he is good, and others are bad.
Arrogance destroys the valuable, and absolutely essential, relationships a leader has with other team members. Even more devastating is the feeling arrogant behavior creates in others. People have no desire or motivation to follow an arrogant leader. Sometimes the arrogance is so repugnant that people cheer when arrogant people fail, even if it means they suffer too.
Consider the Republican Senators being summoned to the White House today to debate national health care. Forget the substance of the issues associated with the debate over nationalized health care. Consider only the single act of Donald Trump inviting 100 Senators to come to the White House for a debate. It happened once before when Trump summoned them to come to the White House for a briefing on North Korea.
It was April 26th that the entire Senate was summoned to the White House for a briefing on North Korea. Everyone assumed that the Senators were coming to the White House to meet with Trump. However Trump only “stopped by the briefing at the Eisenhower Executive Office Building on the White House grounds.”
