I suppose any book that attempts to sort everyone into categories by class is going to be guilty of generalizing and sterotyping. It would be easier to understand the charaterizations if they weren't so terribly dated now - while the copyright is 1983, based on the TV shows cited I suspect the ideas might be a bit earlier. There are things that mention answering machines and microwaves, and it's hard to remember what I thought about them when they were first showing up; and of course all sorts of fashions in houses, clothes and so on have shifted the markers. But much is based on occupations, and given the depth of the changes in the job market as blue-collar jobs went overseas and white collar workers were replaced by computers, there are quite a few observations that just don't make sense any more.However, it's still fairly interesting reading. 25 years ago, I'd probably have given 4 stars - the author does do a certain amount of sneering and superiority that is grating.
