I was just trying to offer a quick explanation/summary of the concepts or the main distinguishing external features of each class, because I see a lot of confusion and wrong self-perception. I see a lot of people saying they’re “mid to upper class” because they can afford a nice home and two cars. Just looking at how much money they have, not how do they have it or whether they can maintain that without working. Obviously to understand class and social stratification you have to read more. I am aware that the upper class are there because of the work of the lower classes and the surplus etc. I’m not obscuring anything, just offering some definitions. Sorry if it didn’t come out that way.
