I'm not sure how this cartel like behaviour works in the UK where every major supermarket has its own range of competing products - and then there is the likes of Aldi that is 90% stocked with brand lookalike knock offs?

There are currently competing narratives in the UK about food prices - greedy supermarkets v poor farmers and the same people complaining then say they shop at Aldi because it's cheaper.

Food is still cheap - it represents a small percentage of people's income. However, in the UK, we are beginning to see that food produced without the benefit of slave labour is somewhat less cheaper than it used to be.
