For me, I definitely came from a working class background.
I am the only person in my family who has gone to university and now has postgraduate qualifications.
I relied on my student loans and part time holiday jobs to get me through uni as my parents weren't able to help financially. I won't inherit anything, haven't had help buying a property.
Now, I own my home and have a well paid, professional job. We go on holidays, mainly UK but that's our choice - usually hiring cottages. We visit lots of places with our son e.g. museums, castles, NT places, restaurants.
My son's upbringing to date is certainly more privileged compared to mine! I also ensure I help with homework, read with him regularly etc. He has swimming lessons and can go to cubs.
I have to admit that part of my reason for only wanting one child was so that we would be able to give him things like holidays/trips out/support with learning etc.
