Chief among the forces affecting political folly is lust for power, named by Tacitus as "the most flagrant of all the passions." Because it can only be satisfied by power over others, government is its favorite field of exercise. Business offers a kind of power, but only to the very successful at the top, and without the dominion and titles and red carpets and motorcycle escorts of public office.
