who governs?

We want to know the answer to the first question because we believe that those who rule-their personalities and beliefs, their virtues and vices-will affect what they do to and for us.
when asked..." who governs?" some people will say " the unions"...and some will say "big business";...and others will say " the politicians".....not all these answers can be correct-at least not all of the time.
The answer to the second question is important because it tells us how government affects our lives. we want to know not only who governs, but what difference it makes who governs.
