This document discusses globalization and employment structures across different countries and levels of development. It begins by showing the production chain for a pair of trousers, with different stages occurring in different countries, demonstrating economic interdependence. It then defines primary, secondary, tertiary, and quaternary employment sectors. The Clarke Fisher model is introduced to show how employment structures change as countries develop from pre-industrial to industrial to post-industrial. Developed countries are shown to have higher levels of tertiary and quaternary employment, while developing countries rely more on primary and secondary industries. Working conditions are generally better in developed than developing countries.
