People always seem to assume that running a country is like running a business, which is absolutely incorrect.  The goal of a business is to make money.   Running a country is about providing services to the citizens.  Different MOs.  Would you take a congressman, and set him loose as the head of say Ford Motor Co.?  No, that would be absurd.
Yet, we have elected a real estate developer to run the most powerful country in the world with zero political experience, and we are expecting great things.
This is what's known as the triumph of hope over experience.
