That’s partly what I am getting at, foxie. The very fact that those things have been identified as class markers speaks for itself.
Also, the old ABC classification system is not applicable to modern life. The wife of a plumber would be seen as C1 in that system, and the wife of a professor as A, regardless of whether the plumber’s wife worked as a surgeon and the prof’s wife as a cleaner. No value judgment is attached to any of those roles, incidentally - they are the Registrar General’s categories, not mine.
The children of the (probably unlikely) couples would also be categorised according to their fathers’ occupation, despite the fact that often mothers have a greater influence on young children’s upbringing (particularly when the father is the higher earner), and it would traditionally be assumed that the surgeon wife would have more cultural capital than the cleaner (rightly or wrongly).
Also, as I mentioned earlier, these days plumbers earn better salaries than many traditionally middle class people, and now that HE has (thankfully) expanded their children have a good chance of mobility, which was not the case when the system (more of a taxonomy, really) was devised, and arguably the child of a plumber would be moving down the scale if they became, say, a teacher or worked in admin at a routine level.
I don’t know the answer to this, but am interested - on the modern housing estates on the outskirts of towns (the 4-5 bed detached box ones), do people socialise based on the husband’s occupation, or do the friendship groups form around proximity or children? My guess is the latter, which again flies in the face of old expectations.
More questions than answers, I know.
