One of the larger unions here in Norway published an article with some calculations detailing how much a beer should cost in a pub or bar in Oslo. Their point was that if it was significantly cheaper than their number, the owners most likely didn't pay minimum wages or some similar shenanigans was going on. I've often since thought other groups, like farmers, should do something similar. I've got no clue how much a small basket of strawberries should cost for the farmer to make a decent living and the pickers to get a decent salary. Same with most other things I buy in the grocery store.
