Well, if you end up working in an office environment most people you will come across consider themselves middle class because they’re white collar workers rather than blue collar workers even if (like most other places, it seems) most of the British middle class tend to live paycheck to paycheck same as the working class.

Also who you’ll meet in social situations will depend a lot on where you live, since last I checked most city centers in England had become way too expensive for even young white collar workers to live in, much less blue collar ones.

Anyways, in my own experience going to live in other countries, whatever happens will be a good learning experience.
