I also think what people buy and expect from their lives have gone up we didn't have a dishwasher/tumble drier/sky tv/mobiles/computers and all the associated costs
far few people had a car (or two)
much less holidays (especailly abroad)
ate out about once a year and never went to cafes
kids played out on the street (no expensive days out/toys/ computer games etc)
no such things as expensivbe baby swimming
baby equiptment was much less/reused much more
house prices much cheaper,
most people also didnt spend so much on furniture
much fewer presents at christmas and easter
Much less clothes and we had to have patches on trousers etc
People hardly ever drank at home, and went out much less,
rarely went to concerts/festival
we had less. bought less. did less.
This is of course a massive generalisation and never buy my kids new clothes/go on holiday but on average as a nation we do far far more.
