I've tried googling the name of this theory, but I can't find it anywhere... I remember reading about the idea that the first world has a vested interest in keeping developing countries undeveloped. This is highlighted in the proliferation of Hollywood movies and the littler support for local representation in media, as well as limiting technology and technological development in those countries, in order to keep them dependent on first world countries. Was there a specific name for that theory, or am I mis-remembering things?
