A recent example of what I’m talking about is that students at several (? - at least one, Wisconsin I think) universities in the US pressured their administrations to drop clothing contracts with Fruit of the Loom unless they allowed workers to unionize in Haiti (again ? - could have been another country in the area).

Which is great, but it would be a whole lot more effective if the US passed laws restricting trade with countries that don’t have good protections for workers in similar situations.
