The statesman who should attempt to direct private people
in what manner they ought to employ their capitals
would not only load himself with a most unnecessary attention,
but assume an authority which could safely be trusted,
not only to no single person,
but to no council or senate whatever,
and which would nowhere be so dangerous
as in the hands of a man
who had folly and presumption enough
to fancy himself fit to exercise it. 
-Adam Smith
