so much nowadays for you need a mobile phone, I get texts from the doctors, for instance, telling me that I'm getting a call from the doctor or to make an appointment for a blood test, and during lockdown, I had physio via a mobile,a bit like zoom but NHS zoom, I'm regularly doing a health-related course on teams on my phone, without internet access I'd not be able to access any of that.
Look at the price of postage these days, being able to email stuff saves on that, and being able to do banking online means you don't need to pay for transport to a branch. If you are in temporary accommodation or indeed nowadays much accommodation, there is no landline. I have a landline with my broadband but actually pay less monthly for my mobile and data, as having mobile data means that life is easier, I can go to places I don't know and look up buses and maps, I don't need to buy a map or find the bus station. I can do simple work-related tasks when I'm waiting for a bus on my mobile
I've worked and volunteered with people who are jobless, on benefits, and asylum seekers. Some of those unfortunate people hardly had more than a kettle and a ring and microwave, to cook on let alone fridge space or a freezer. or a big pan, or a wooden spoon or whisk or even a sharp knife. Or space to store even small bulk buys of food even if they were able to do it. Basic cheap filling things need lots of ingredients to make them tasty, and it can take time to build up a stock of such items, and basics like flour or cornflour to make sauces. I love lentils, often make a lentil soup because I enjoy it but you need other things to put in to it for flavour and balanced nutrition. Plus buying in small packets is a dear way of getting them, not everyone has access to an Asian shop to get large cheap bags full. Veg soup can be easy but it can be nicer if you are able to blend it, so where do you get your blender. Where I live I do visit Aldi but I'm only able to do that because I have a car and pop in when I have to go the ten or twelve miles for something else workwise. One person on a bus would cost nearly £9, In some places, the costs of buses are such that it may be well cheaper to take a taxi if you also have children that have to be paid for on the bus, and it may mean you can bring back shopping that you couldn't possibly carry. If you have no transport you are limited to what you can carry. I'm lucky that I can get to Aldi, when I was in a village with no car and with local small shop and with few buses and the ones there were didn't actually go anywhere that useful, that was hard getting the shopping.
I'd agree that cooking is not taught as it used to be, but although I can make all the different types of pastry nowadays I'm afraid I buy it ready-made most of the time, well puff pastry anyway. Even shortcrust it can be more convenient to just defrost a small packet of pastry. But honestly, if you are short on time and money and you can get a cheap pie you are going o go for that
So many do not know what poverty is like.
