Housing costs lower.
No right to buy if you owned a council house and they were sought after, to get one your old home was inspected and they looked at things like if you had clean sheets - yes I know I look to be off topic - but council houses used to have a huge back garden because it was intended you would grow your own veg.
Children went to local school and walked, only had uniforms at grammar schools mostly so no transport costs for children.
No foreign holidays - a week at the seaside if you were lucky.
Lower heating bills - you can stick a lot of rubbish on a coal fire, of course your kids woke up to ice on the inside of their windows.
Most people worked locally, not many had cars.
Teenagers contributing to family income from 14 or 15, few went to school until 18, and uni was incredibly rare. Teachers were trained in their local collages not at uni.
It was worth wile mending clothes because new ones were expensive so not as much bought on a whim - not sure how much that contributes.
Shops closed in the evening and all day Sunday meant you had to meal plan.
Virtually no one had alcohol at home, or if they did it was a treat (my mum used to sneak a bottle of stout in to her grandmothers, hidden under her coat so neighbours couldn't wee),
Games were made of card board and bought once a year
