Go here if you want to read something David Brooks hasn't:

...rich country trade liberalization is generally a quid pro quo for concessions from developing countries. Many of these concessions, such as the enforcement of rich country patent and copyrights, impose substantial costs on developing countries. In addition, trade agreements often limit the ability of developing countries to pursue the same sort of industrial policies that rich countries used in order to develop. It is entirely possible that the cost to developing countries from paying copyright- and patent-protected prices to rich countries will equal or exceed the gains from rich country trade liberalization, as suggested by preliminary research on this topic by the World Bank10. If trade agreements simultaneously foreclose successful development paths for poor countries, then the world's poor may end up being the big losers from commercial agreements that promise trade liberalization by rich countries.
