I disagree actually @sippingcoffee. I'm doing a PhD and did a module which looks closely at social class ... and it's more complex; class and status do overlap. Bordieu's concept of cultural capital springs to mind on this topic if you know it?
I would call myself lower middle class actually if i were to put such a broad label on it (there are msby other ways of definding class which are often more specific and succint). My roots are very much working class (I was born in Birmingham, went to local comp, Dad was a mechanic, I was on free school meals, my family were pretty poor and at one point both my parents were unemployed at the same time and it was tough for everyone).
But now I live in Surrey, household income of over £100k, 2 cars, went on a month-long honeymoon to Hawaii and am a teacher in a top indepedent school. Got two masters degrees and soon a PhD, taught in a university and a Swiss 'finishing school' (they even teach etiquette classes there- bleugh!) and travelled extensively. Will be sending my son to private school.
My experiences of life for my first 18 years are totally different to my experiences or life in the past 14 or so. I'm not working class anymore, even though my roots were. I identity more with the middle class and anyone who knows me thinks I'm actually very posh and assumes I was privately educated and from a privelige background etc. But I think living two very different sorts of lives is a bit odd... and there are things that make me feel not quite as middle class as my middle class friends. In some ways I feel a fraud when teaching at my posh school. E.g. I didn't go to the theatre until I was 18, and didn't set foot on a plane to go abroad until I was 21, didn't eat out in a restaurant until I was around 17 etc. My husband is frequently incredulised about those sorts of things... but he had a much more privelige upbringing than me.
Class is a very interesting topic but incredibly complex and even top academics in this field don't have a consensus.
