Americans aren't stupid, they are distracted.  It is an important distinction.  It takes time to research, learn, and develop logical thinking techniques.  Quite frankly, most Americans do not have that kind of time.  (((They))) set the system up to prevent it.  Have the Americans work 40-60 hour weeks, prevent young learning by forcing children into day-care, fill their free time with netflix, facebook, video games and football, and then remove philosophy from the school curriculum while dumbing down the testing requirements so the stupidest kid in the room can still pass with an above average score (think about the math behind that last one).
