Both outsourcing and sweatshops show how comparative advantage and trade work. Outsourcing has a bad reputation in the U.S. but it is simply comparative advantage in action. Sweatshops also have a bad reputation. The first video deals with outsourcing. The next 3 videos and one article discuss why the push to end sweatshops might not be a good idea.
