Well not really. It's a bit difficult these days to buy a house with an outhouse instead of a fitted bathroom. Most mortgage lenders won't lend on a property without a fitted kitchen, either. So you have to buy a house that has these. Lots of houses just happen to have ensuites, the designers of newbuilds don't survey people, they just build them like that.
I'd also like to see what Social Services said about a family living in a house fit for the 1920s with an outhouse and no fitted kitchen, double glazing, electricity, indoor running water or central heating.
It's likewise difficult to buy a car at 1970 prices (even adjusting for inflation) because cars these days cost so much more to produce, to stop them being deathtraps. Side airbags, disc brakes, catalytic converters, seatbelts etc all cost more during production. There's no option to buy a car from this century that doesn't have these things because we now think that would be too dangerous. With subsequent decades of public transport cuts and urban newbuild sprawl since the 60s/70s into areas that were never on a bus/train route, people generally need a vehicle outside of major cities. Especially now that industry has left most towns so the majority of people can't just walk to the pit/factory to work.
With two people expected to work to survive, nursery fees are now needed for all children the family choose to have. Having children wasn't even much of an active choice in the 50s or early 60s, people just had them and society was set up for it. Now we're told it's a choice we make when people want to rub it in our faces, when for every other species on the planet it's just biological fact, so society have made it extremely difficult and expensive for people to actually have and raise children with so many things that society says they must have.
The NSPCC gleefully abhor situations where a boy and a girl are sharing a bedroom so unless you luck out and get two girls or two boys, that's a non-starter for most people, too.
So the only one I'd agree with you on is holidays abroad which absolutely no one needs.
The cheaper options just don't exist anymore. There isn't a choice. It's pay a bomb for the thing in front of you or don't have it at all and suffer the consequences, which in some of these cases would be significant.
