This essay by Murray Rothbard holds particular relevance as the Trans Pacific Partnership continues to be negotiated in secret.
Yet Nafta is more than just a big business trade deal. It is part of a very long campaign to integrate and cartelize government in order to entrench the interventionist mixed economy. In Europe, the campaign culminated in the Maastricht Treaty, the attempt to impose a single currency and central bank on Europe and force its relatively free economies to rachet up their regulatory and welfare states.
In the United States, this has taken the form of transferring legislative and judicial authority away from the states and localities to the executive branch of the federal government. Nafta negotiations have pushed the envelope by centralizing government power continent-wide, thus further diminishing the ability of taxpayers to hinder the actions of their rulers.
