The economic policy dominant in the Europe of the 17th and 18th centuries, and christened “mercantilism” by later writers, at bottom assumed that detailed intervention in economic affairs was a proper function of government. Government was to control, regulate, subsidize, and penalize commerce and production. What the content of these regulations should be depended on what groups managed to control the state apparatus. Such control is particularly rewarding when much is at stake, and a great deal is at stake when government is “strong” and interventionist. In contrast, when government powers are minimal, the question of who runs the state becomes relatively trivial. But when government is strong and the power struggle keen, groups in control of the state can and do constantly shift, coalesce, or fall out over the spoils. While the ouster of one tyrannical ruling group might mean the virtual end of tyranny, it often means simply its replacement by another ruling group employing other forms of despotism.
