I think you need to remember that 1970 was only 25 years after the end of the war. Many big cities that were bombed were still reconstructing. I was born in 1965 in Liverpool, there was a bomb site in the road I lived in, I had friends who lived in pre-fabs which were put up as temporary accommodation just after the war but were still in use 35 years later, we quite liked them, they had proper gardens, we had a back yard.
Looking back it all seems very grey, but at the time expectations were just different. We were working class but homeowners, we had a car, eventually we had a colour TV, one phone in the hall, We didnt have a washing machine until I was in my teens, everyone I knew went to the lauderette. My grandparents did not have an indoor toilet or any sort of bathroom until I was 18, ie 1983. Central heating was a luxury. A take away meant chips, KFC was a huge treat, McDonalds hadnt arrived. We never ate out, going out for coffee in a dept store was a rare event. We did have a summer holiday, to North Wales. Food was pretty much meat and two veg, spaghetti came out of a tin and was either hoops or Alphabetti, rice was a bit exotic. Three TV channels, channel 4 was terribly exciting.
I remember power cuts, three day weeks, strikes, the drought of 1976, and going to the stand pipe for water.
Its world away from the life my son enjoys. In contrast it looks very poor, but growing up I didnt feel poor, we were fed, housed, clothed, had what we needed. I did babysitting from age 14 so had money for clothes, make up, records.
The 1980s were very tough though, high unemployment, neither myself nor my brothers had any prospect of work when we left school and there is 10 years between us. They went on to job creation schemes and found work eventually. I had ALevels so moved away to university and never went back. I did go to Coventry which was as grim as Ghost Town describes.
There was real poverty then, my dad made deliveries to tenement flats known as the Piggeries, for very good reason. There is real poverty now.
But overall expectations were just different. There were rich people but not what might be seen as excessive consumption, and no shiny celebrity culture to compare our grey ordinary lives to.
