What's Hot & Cool?
In the course readings, Friedman suggests that American prowess in the global market will be effected by three factors: the numbers gap, education gap, and ambition gap ("The Quiet Crisis" 256). Some may note that while Freidman's argument definitely has weight, it is still a fact that U.S. culture is seen as the standard to aspire to, and is therefore the cool/hot commodity on the global market.
What is the definition of "cool" and "hot" in your host culture? Where does it come from?
Please remember that this is an academic forum, so the question is not meant to provoke sexual commentary :) I would like you to try and use specific examples, and if possible, pictures, to respond to the question.
