Has imperialism become more or less oppressive as the world has become more industrialization

 Imperialism has been the most powerful force in world history over the last four or five centuries, carving up whole continents while oppressing indigenous peoples and obliterating entire civilizations. Yet, it is seldom accorded any serious attention by our academics, media commentators, and political leaders. When not ignored outright, the subject of imperialism has been sanitized, so that empires become “commonwealths,” and colonies become “territories” or “dominions” (or, as in the case of Puerto Rico, “commonwealths” too). Imperialist military interventions become matters of “national defense,” “national security,” and maintaining “stability” in one or another region. In this book I want to look at imperialism for what it really is.
