Mass Suicides at Chinese Microsoft Plant vs. Free Trade

Today in class we were asked whether or not we supported free trade. At the time my answer felt obvious, of course I support free trade. This was probably influenced by our first reading, from Martin Wolf, who makes the hypothetical argument that it makes little sense for America to set prohibitive barriers that create 50 separate economies. In same way, it doesn't make sense for the world to be divided into 200 separate economies. This logic seemed compelling at the time, but the more I think about it, the more unsure I become in the free market logic. Take for example the afore mentioned article. The details are a little sparse, but its slightly perturbing to think that in order for us to consume products for a "reasonable" price here in America, our goods need to be created by Chinese workers toiling in a sweat shop. Not just toiling, but treated poorly enough to consider mass suicides in order to improve working conditions. This article makes me reflect on my earlier assuredness in the free market, perhaps I do support some sort of regulation after all?
