What is stake for workers in rulers’ debate on trade pact?

Excerpt:

....Workers should oppose all tariffs and other barriers on goods coming into the United States and other imperialist nations. The workings of the world capitalist market guarantee the plunder of the semicolonial world, Barnes notes, not primarily due to “unfair” terms of trade, but as a result of “the differential value of labor power and the gap in productivity of labor between the imperialist countries” and those oppressed and exploited by imperialism.

Working people need to chart a course independent of the bosses and their parties, reach out in solidarity to workers around the world and refuse to be sucked into the nationalist anti-free trade campaigns that would pit us against each other.
