to be fair, the people who are accused of being 'I'm alright Jacks' 'insensitive' 'dismissive' etc are probably replying to OPs opening sentence "To think a normal standard of living is out of reach to the majority of the population. People are barely surviving as is." Which is clearly an exaggeration. Doesn't mean people don't understand that there are some people who might be barely surviving and a lot more who are struggling, just that they are refuting that it's the majority of the population. Which is fair enough.
I actually think it's really valuable to get threads like these with examples from a wide variety of the population. Otherwise people only get their information from their own close circle (which is almost always a bit of an echo chamber, just look at the millions of posts on here that include "I don't know anyone who...." "Everyone I know...." "where I live...." etc.). or the media, which vastly misinforms and overexaggerates.
Just look at some of the crises of the last few years - everyone mass piling loo roll etc at the start of the pandemic - entirely led by media photos of empty shelves, there was actually sufficient products for everyone (or would have been if people hadn't panicked). Same with the ridiculous queues and fights for petrol - there were minor, short, disruptions to the supply chain, in a very few parts of the country, if the media hadn't published it and escalated it to mass panic, the rest of the country wouldn't even have known about it and wouldn't have bought any more than normal.
It's actually really useful to have realistic first hand accounts of other people's experiences - from a wider overview, information that actually the majority of the country might be cutting back a little but is generally managing ok could influence where help should be targeted - e.g. the energy payment of £400 per household was probably the 'fairest' way to do it but should it instead have been aimed at giving more help to the lowest income brackets?
But also from an individual perspective - people have been mocked on this thread for the 'you just need to retrain' suggestions (and same for 'just move to a cheaper area' neither of which are a magic fix all solution without any drawbacks) - but generally people have very little idea of the variance in wages between different sectors/house prices in other parts of the country etc. So it is useful to see someone else who might be in otherwise similar circumstances to you (similar age, DC, qualifications etc.) who is doing okay and think 'okay, how do I get there, are there options I haven't considered,' etc. Even if when you do consider them they might not work for you!
E.g. I used to work in a job with several London and various regional offices. Because a lot of them came from London/the south east their 'norm' was that owning a house was completely out of reach for anyone their age. Everyone they knew except for the odd person in a really good job was still living with parents or in houseshares. They obviously weren't stupid, they knew that property was probably slightly cheaper outside of London, but thought that the London weighting allowance basically counteracted that, so even if housing was more affordable elsewhere it would still be out of reach unless you bought somewhere completely rough or in the middle of nowhere. It was a bit of a shock when they did placements in the regional offices (themselves in nice, big, cities with lots to do) to realise that not just a few, but the vast majority of staff the same age as them doing the same role COULD easily afford to buy houses and generally live a much nicer lifestyle on the same wage.
Does that mean they all should move straight out of London, obviously not. For some the benefits of living there, whether it be for the London lifestyle/experience, or staying close to their families, or the better career options, was worth it. Which is fine! But at least they were aware that the were other options out there that they could bear in mind. Otherwise it's too easy to just read the headlines stating that house ownership is impossible for millennials and just accept it.
