OP, please don't lump us all together. We aren't all too stupid/selfish/ wilfully ignorant to realise that certain things - especially the cost of housing in many parts of the UK - are a lot harder for our children than they were a few decades ago.
Yes, other things have improved, Most goods are relatively considerably cheaper than when most of what you bought was made here and not in China - but I can't think that makes up for the relatively vastly increased cost of buying a flat or house to put them in.
OTOH it's true that expectations in some respects are often higher, but then that's often true of the generation gap. The things one generation take for granted would have been luxuries to the previous one.
My granny never had a TV, and her own mother never had a radio - despite loving listening to it when she was at her children's houses - my mother often said she bitterly regretted not even thinking of giving her one. Though of course it would have been a major expenditure then. And for most of her life my great granny had only gas lamps.
In the mid 70s, shortly after we were married, my Dh bought a state of the art colour TV for his parents, who until then had only had a black and white rental. It was vastly more expensive, comparatively speaking, than such things today.
Nowadays, sad to say, it's frequently more likely that parents will be treating their grown up children to things they can't afford, often because of the cost of mortgage/rent/the ruinous cost of childcare.
And yes, I am well aware that not all parents are in a position to do so, however much they might want to.
