My experience isn't as drastically different as some have posted about, but yes, I feel it.
I grew up in a northern working class family, with my dad as the main wage earner. We didn't go to childcare, my mum was at home. My mum worked various part-time jobs as my siblings and I got older but it was always at weekends or when we were in school.
We lived in a three-bed semi with a loft conversion added later. There was a back garden, big enough for my dad to build himself a workshop and still leave the rest of the garden a decent size.
My dad always had nice company cars and paid extra so he could upgrade. We had a holiday abroad every year, with several UK trips camping or in caravans for long weekends.
In contrast, my husband and I both work full-time. I am the main wage earner with career prospects. My husband has been in the same job for nearly 15 years, but stays because he works shifts that mean he gets a block of days off work.
We rely heavily on paid childcare.
We rent a three-bed terrace, with a small back yard that is unusable due to disrepair and a dilapidated shed taking up all the space.
We have only had a car for a year but it's an old banger. I actually don't care about that as long as it's driveable but I've not passed my driving test yet and have concerns about whether I can handle it.
We've never been on a holiday abroad and have only been on one UK holiday.
I couldn't work for years due to ill health and have only been back working for three years, but I'm doing really well and have been promoted in that time.
Our children are autistic, so that's also affected our finances a lot. I was physically well enough to go back to work sooner but we were in the middle of all the autism diagnosis stuff for my oldest and he was doing better with me at home, so I waited.
I do think we'll reach the standard of living I enjoyed as a child, but my parents had it at a much earlier stage, and it was easier for them. They didn't suffer from having a parent at home, whereas we did and we weren't quite at the stage of needing a food bank (benefits fuck up!) but it was a very close thing.
We're getting there. The main thing I wish I could give my children is access to a garden. I don't even care about owning our own home any more, although the security of it would be wonderful.
