I'm struggling a bit to put two and two together here. Maybe it would help if you could tell me what you think "middle class" should mean. And I think because it has come up in this thread as well, also where "upper middle class" is. I think the obvious thing to do is to define it by income percentiles, but you don't seem happy with that (or maybe you just disagree on what the floor and ceiling of the percentiles should be?), and I'm open to the idea that something else matters more.
