Many countries have organised themselves into groups that have worked to in various ways to protect and enhance their domestic economies, their social status and level of development. Examples include the G8, the EU, NAFTA and the WTO.

The free trade that takes place within this bloc can often increase competition creating more businesses and reasonable prices, or they can offer subsidies to assist in the development of a particular sector, such as in the Common Agricultural Policy.

With the EU seeing the benefits of the grouping there is greater polarization with the rest of the world and these people are getting further and further behind. Furthermore, with tariff cuts in place within the EU, they are less likely to
