This is an interesting thread. I grew up in the 70s/80s and we definitely weren't poor, lived in a nice detached house in a nice part of town. Dad was a railway inspector, Mum was SAHM.
However, the only difference I can really remember between me and most of my mates who lived on the local council estate was that we had a phone and went abroad once a year.
In fact they had colour telly long before me, and nicer clothes too.
None of us had central heating until well into the 80s then we all kind of got it a the same time.
Our childhoods seemed exactly the same to me and we played in and out of each others houses, got the same stuff for Christmas, same pocket money etc.
I can remember some extremely poor families on the estate, but that was usually due to the sheer size of the family. One family had 21 kids!
After school the main difference was people on my road went off to college/uni. Most of mmy mates on the council estate went out to work immediately.
But really we were all the same. 3 good meals and a warm house.
