If you own a company that's headed for bankruptcy due to mismanagement and corruption, you don't promote a 32 year employee to run the company.  You bring in an outsider with fresh eyes to tear down the walls and rebuild the company.  

As for President Trump, the people of the U.S. were tired of electing people who were "experienced" and who spoke with silver tongues only to put the screws to the middle class after they got into office.  The people decided to make a change and elect someone who would tear down the walls.  I believe in the collective wisdom of the American people.  Although President Trump has consistently beaten the odds and accomplished what nobody in the past, present or future would do, ultimately I don't think he'll succeed. The forces against him are too great and if he ever gets close to draining the swamp, they'll get rid of him...one way or another.
