I don't know the answer to the convenience of free trade, but I think there is different kinds of international trade and we talk about all them as if they are the same thing.

For instance, the more successful economies Japan, Germany, China, Korea didn't follow the same model of free trade that has been "suggested" to the South American countries. In fact, in the eighties everybody complained how difficult was to access to the Japanese markets.

The other thing is that is very different free trade of commodities vs. free movement of capitals but normally it's sold like it's the same. If you are in Peru is probably a bad idea get a lease denominated in U.S. dollars, no matter how good the deal looks now.
