The key thing you need to know when confronting the U.S. class system for the first time (apart from the fact that Americans like to pretend they don’t have one) is that the term “middle class” covers most of the population – what Americans like to call “ordinary folks”. Thus, if you are a truck driver, or a teacher with 15 years of experience, or the manager of a company employing 250 people, you are middle class.

Above the middle class are the rich, who divide into the five per cent, the one per cent and the 0.001 per cent, with extra-ordinary folks like Jeff Bezos, the head of Amazon, or Mike Bloomberg
