Mr. Trump's core problem is that he comes from a business background which is strictly heirarchical. When the CEO says do something, underlings are quick to respond. If they do not respond, they are moved out. 

Politics is completely different. Politics requires the politician to create alliances, to find solutions to complex problems.  You do not achieve political goals by issuing executive orders, or alienating competing players. Trump's failure to recognize these differences will likely prove to be his undoing.
