is this a carnivore thing ?
Not sure. IME supermarkets keep the price of meat artificially low, while veg suffers in both cost and quality (and variety).
The difficulty is that, as a nation, we have bought massively into the "food must be cheap" mentality. We have also pandered to the idea of one big shopping trip per week to a supermarket and have adjusted our lives for this.
The food we buy reflects this – "bread" that lasts a week anyone?
But, as a general comment on the cost of living – I find that inflation has been much greater than the low figures that RPI (and even CPI) suggest. Combined with salaries and wages remainiung at least static or even being heavily reduced to avoid unemployment, the perceived cost of things has gone up.
The reality is that, for a significant number, nothing much has changed except their perception of how expensive things are.
