And, as far as classes go, there are more than three. Due to education of so many people, and different jobs,there have become more than three classes. When I started working, there were about 9 classes. High upper, mid upper, low upper, high middle, mid middle, low middle, high lower, mid lower, and low lower classes. The distinction between each of these classes has become very grey. How do you differentiate between low upper and high middle? Or any other two adjacent classes? Today the whole thing has become grey, with just as many classes as you have people. It has nothing to do with politics, unless you are talking about a communistic society, where everyone is paid the same. Even there, there is a certain amount of distinction.
