For Locke, the problems of economy were closely related with the government. He thought that the economic prosperity of England was realized by ‘ordering’ trade. Trade consisted of two fields; one was manufacture, and the other navigation and commerce. And what rotated ‘the wheel’ of trade was money. It was required that landholder, broker (merchant and moneyed-man), and labor took their own part as a component in the circulation of trade. He did not intend to defend their particular interests, but thought about totally the problem of trade in terms of pursuing the public good.
