Convergence theory has been charged with a Western, middle-class capitalistic bias. As a theory of industrial growth, it holds that industrial workers everywhere adjust rapidly to factory discipline, evolve similar patterns of social participation inside and outside the workplace, increase their involvement in urban-industrial society as they increase their contact with modern technology, and develop similar working-class mentalities. Since most studies that confirm these generalizations have been conducted in the West, Korea provides a tough non-Western case for convergence theory. When Korean automobile workers were compared to auto workers in four Western-oriented countries, the Koreans adapted just as quickly to industrial and related social systems. Their rural background and Confucian heritage did not interfere with their adaptation. Like workers elsewhere, Koreans who were most exposed to modern technology participated most in social systems inside and outside of the factory. Despite their socialization to support hierarchy, Koreans quickly developed a working-class mentality. We conclude that some tenets of convergence theory are robust.
