I find this fascinating. I would like to think I'm working class, but probably realistically bordering middle class.
My mum was a duty social worker, but not a very senior manager, my dad was a community worker, then manager and now a freelancer. Grew up in a small ex-mining village. We never had any spare money and grew up on findus crispy pancakes and oven chips. We went abroad twice when I was a child, once was with an inheritance when a grandparent passed away. I got called 'posh' at secondary school but at uni I was amongst the poorest and people laughed at my local accent.
I now have a mid-senior job, dp lower paid healthcare worker. We do have foreign holidays and trips away at least once a year. Mortgage, 2 cars, some branded clothes, weekly shop online, have a cleaner, eat out about once a month. But we do need to budget quite carefully. Family could help us if we got stuck financially but not indefinitely.
Our dc have never been skiing for example, we don't have savings for uni for them and paying for driving lessons will be a struggle. We could never even contemplate private school.
Are we middle class? Working class? I don't know!
