In the West, globalization has also led to the rise of a service economy. In the US and Europe, most people now work not in agriculture or manufacturing, but in some kind of service sector. Healthcare, retail, education, entertainment, information technology, internet videos about world history, etc. And that switch has really changed our psychology, especially the psychology of upper classes living in the industrialized world. I mean, to quote Frederick Jameson, we are so far removed from the realities of production and work that we inhabit a dream world of artificial stimuli and televised experience. Think of it this way, if you had to kill a chicken every time you visited KFC, you would probably eat fewer chickens. Another change of psychology?
