space The prices they pay for southern european stuff is peanuts - farmer typically gets around 60 cents a kilo for standard white table grapes and its been that price for years. I used to grow almonds - prices were shit - if I earned 300 euros from 180 trees I was doing well, but not worth the effort you have to put in to grow them (irrigating, pruning, weeding, harvesting, shucking by hand). The supermarket markups are enormous. There's your problem. That and importing plastic shit from the US, and exotic and out of season stuff from the Antipodes and Latin America. Growing stuff locally is part of the answer, but you try growing avocados or almonds in Bury in January. Although if heat continues to increase that may not be a problem.
