When it only helps a small number of companies, we raise our voices. Imagine an international community in which tariffs are eliminated, investment could move freely, government procurement is open to all bidders, and services are freely traded but in which an international minimum wage is established, a common set of health and safety regulations is developed, respect for worker representation is enforced via tough penalties for non-compliance, and procedures are developed for mandatory employee consultation that do not circumvent the trade unions. Then imagine an open process in which 34 countries were negotiating the treaty to develop that imagined community. Obviously, the devil is in the details. But, if such an imagined community had high standards for environmental protection, public health, and agricultural production we would be favorable.
Protectionism is a red herring.
It only confuses the debate. We realize the economy is always innovating, always changing. We want only to increase social justice. The goal is not to keep jobs in one place. It is to give working people a voice at work.
