This sort of crap amuses me.
I identify as solidly working class despite:
Having a professional job (formerly in banking now in reinsurance);
Living (at weekends) in a detached former vicarage;
My STBXW driving a Landrover (I have a now ancient German saloon);
Kids attended private schools (prior to moving house); and
An aga (which is in a kitchen the size of our first flat).
I'm not stealth boasting, I'm just pointing out that these things might be seen as solidly middle class, but despite it all, I was still born and raised on a council estate in the East end. I have an estuary accent, will not eat olives and think that many of the 'trappings' of middle class (like the crap in the article) are for those that feel somehow less secure in their lives.
The most pernicious element of this whole class debate (to me) is that being middle class is somehow better than being working class. Your candle will not burn any brighter because you've snuffed someone else's out. I wouldn't want any of the middle class masses on here to ever wake up and think they were somehow better than me (or anyone else)
As you were.....
