Seeing this written here was pretty hilarious to me, I'm not sure if you're aware of this, but one of the central parts of the TPP was exactly the point you're making: To expand tighter labor and environmental laws into places like Vietnam so American workers aren't competing against foreign workers whose government is willing to destroy their health and environment to undercut them in price.
The expansion of American copyright laws that the EFF is so against, is mainly there since selling America IP ( both cultural and intellectual) to foreign customers is one of the biggest sources of export income for American corporations and thus a big source of wages for their American employees. You of course can't sell a Disney DVD or a software solution to someone in Vietnam if it's legal for them to just copy it whenever they want.
