I went to a terribly conventional middle class boys Grammar School. In my year we had one Indian, everyone else was white caucasian.
We had 2 boys who were living with a single mother, everyone else went home to two parents.
In the 6th form one lad got his girlfriend pregnant.
Another had an affair with the wife of a teacher.
About 70% went to University or into a "blue chip" Company training scheme.
At home most of us lived in 1930s and 1950s semi detached houses. Some lived in council houses (social housing today).
Some had less than wonderful neighbours, but as DW said, everyone cared about the way people behaved and everyone "knew their place".
Even the settled travellers in the council house across the road caused no problems: he was a used car dealer working off abandoned land nearby.
At the end of our road was a small estate of pre-fabs. Most of the tenants had nothing, but it was far from a slum.
At school we had all male teachers, many with WWII service. The Deputy Head, Guss Hillier, spent from the fall of Singapore to the end of the war as a guest of the Japanese. He had memorised all of the book of 4 figure log tables: one amazing Maths teacher, one seemingly stern Deputy Head with a heart of gold.
Looking back to those times is pointless, but they contained some important truths.
Respect your fellow person
Work hard
Expect no help from anyone.
Enjoy life.
