If people spent the same amount of money on housing as they are paying for food, maybe you’d have a point. Even in the link that you’ve provided, people calculated that housing is about x6.1 median salary today compared to x2.7 in 1977.

Ah yes, as any statistician will tell you - 10 items from one shop is more than enough to determine the impact of inflation over 50 years.

It absolutely won’t cost £22 quid, that’s CPI adjusted of course if you read the comment you’re referring to. But yes, in real terms (asking honestly do you know what that means? your comment seems pretty ill informed) food is cheaper. So are some other items like consumer electronics. On the other hand housing and utilities (you know the majority of a household’s spending) has advanced well ahead of inflation. Hence “cost of living crisis” which maybe you think is imaginary.

Worse, while average earnings have outpaced inflation the bottom end of the distribution has accrued almost none of that benefit. Massive increases in inequality mean that while for the comparatively well off (and the very well off) things are mostly fine for a sizeable chunk of society life has been getting materially harder.
