That's assuming higher wages can be afforded. The salad grower I know operates at such tight margins that she can't; she's paid by the supermarkets and can't demand higher prices in turn, she gets what she is given. I can support what you say, Walter, about 'misshapen veg' by the way - she's had a whole crop of lettuce rejected for not being aesthetic enough. Also agree with NS, Tesco seem to be addressing this with sales of lumpy carrots and so on.
The jam people in Essex will be hit by the pound as they export. So I doubt whether they can buy in more expensive labour. As they have said, it may well be cheaper just to import soft fruit.
What a mess.
