Possibly, or you can pick up the same cost by paying the economic cost of the food that is produced, or you can accept lack of food security.
Hadn't you worked that out before you voted Brexit. Or is it only now that you are starting to think through the consequences?
Yep.
Unfortunately, our agricultural sector is very reliant on cheap Eastern European labour, and it isn't the case that this displaced the Brits doing the jobs either. I'm not saying there are no instances of that happening, but there were problems getting enough British people to work in the sector pre 2004 also.
One hears people, often Brexiters, saying we'll just have to learn to pay more for our food in that case, that when there's a labour shortage farmers will need to pay what's needed to attract workers. The problem is, we won't 'have to' do that at all. If imported food is cheaper, that's what people are going to buy.
I am not saying this doesn't frighten me, btw. I'd prefer to have domestic agriculture. But we are going to have to face up to the possibility that we either need lots of cheap migrant labour or government subsidy, either to farmers directly or to allow British people to actually move to areas of high labour demand with their families to do the work, and accept that they'll be seasonally unemployed.
