Earlier quoted context omitted.
Handful of products? In Finland, at least, much of the grocery market is controlled by two dominant players that more or less control the entire supply chain for many products. Both have been profiteering like crazy lately, and for most people there's no option than their local supermarket.
Supply chain - the materials that go into producing a good or getting the finished good to market. There were no supply issues during covid with many, many products. Yet those prices went up too, even in a country with a high level of competition. Why?
We as in "society"), have assumed this would be solved by some healthy competition. It's just that we optimized society for maximum short-term gain rather than a market where newcomers are welcome. As a result, the players that are already in the game are free to ignore the forces society assumed would keep things running smoothly.
