When I was young, DM couldn't work because there was no childcare. DF had a company car and DM had a really crappy one (always very old and often unreliable, the worst had a plank across the back floor to prevent small DCs falling out through the 2 holes onto the road.....but even the best was quite bad). We went to the big city for our weekly shop as the company car had petrol and they could go to the decent supermarket rather than paying village store prices, and also go to the free library weekly. They would buy half a cow in the summer and freeze it for winter meat. We grew a heck of a lot of our own veg, and fair amount of our own fruit. And would buy apples in bulk from a fruit farm, and other veg in bulk from a local farmer. Cakes or buns were only ever in the house if DM (or a DC) had baked - never from the shop. We foraged in the hedges for wild strawberries, blackberries, damsons etc.
We did have a holiday every year - in a SC house in this country, with HM picnics for every outing, which were mostly trips into the countryside or to the beach near there. The first time I was on a plane was for my honeymoon.
DM sewed a LOT of our clothes, there was also a lot of hand-down clothes for younger DSiblings, and we also got hand-downs from DAunts as we grew big enough for those.
DF did the maintenance on the house, and when he needed to extend into the attic, he did most of the work himself with a couple of neighbours. Painting, plumbing, plastering, electrics, woodworking - he did it all.
We had times when dinner was bread and butter. And school lunches were an apple for break and another apple for lunch.
Yes, they had bought the house we lived in, but at interest rates of 17% and no hope of moving anywhere better or bigger. We didn't ask for money as we knew there was none there for books or toys or clothes from a shop or sweets - I had a weekend job to pay for clothes that weren't my school uniform and occasionally going to the pub when I was a teen.
And on nursery costs, mine were 1400 a month when DD was in creche - 15 years ago now. Yes, I was lucky it had changed that creche was available so I could stay at work, but that was still less than the cost of the mortgage (2400 per month) that DH was covering - for a very average 3 bed semi, and a full 25 year term.
So it's not so different for previous generations.
