Mrz - like your compatriate here , you do not seem to quite grasp who the "middling sort" to use the olden phrase (middle class) really are. Maybe that is why you see yourself as working class?
The middle classes are a broad group. In the 20th century they certainly expanded considerably with beurocracy and public sector work , at least in the lower ranks. I would hardly define the real middle class as "white collar" workers or public sector workers myself , although in more recent times I suppose they have become what could be descrived as the lower middle classes . Such a group most sociologists I have read agree have more in common with working class than with middle class both in aspiration and lifestyle, hence they have been known by the media types and the ad men as "C1 and C2".
The middling sort are the true middle class- professionals and larger business owners. These can include bankers ( those who get the big bonuses) and stockbrokers and certainly university lecturers, doctors, accountants, solicitors etc. I was amongst those before marrying and needing to put my family first which is when I switched to teaching for the hours and holidays) .
Yes, I guess top civil servants and public servants are there as would be the top brass in the armed forces but not the vast majority of those in white collar and clerical type jobs. These top people do not by and large suffer from recession. They may cut back a little but never suffer unless through their own mismanagement of their affairs. The unemployment tends to take place on the fringes in the lower middle class and amongst the working class. Hence my original comment.
I am a member of the middle class. My parents came from that group. I was educated accordingly. I aspired accordingly and my lifestyle follows through as does my housing situation and all other thngs (I suppose). I see myself in those terms because I do come from that group. I married into it also. Teaching is just something I do now. It does not determine my lifestyle as it happens.
I do not intend to sound snobbish but no doubt I will get accused of same.
Saying one is middle class and then describing said group is rather like bot being able to say much about how we could further the situation in state schools and how to deal with EBD's etc. Its not politically correct top be middle class I know.
