my way of looking at this kind of thing is if british farmers can't compete with meat imported in then they are doing something wrong... is something is expensive for no real reason then noones gonna buy it.
i remember my ex insting we get our milk from milkman to 'support his job'. i explained you can get it cheaper from supermarket but she wasn't having any of it... turned out he was unreliable so as well as paying a fortune we never got what we ordered.
like expensive farmers, a milkman is a obsolete job that will die out....
competition in a free market economy is a VERY good thing... stuff that don't satisfy the consumer dies out to make way for things they want (ie - usually cheaper)
I'd never get personal feelings like 'feeling sorry for poor expensive brit farmer' change my buying habits... if they can't compete then they will have to find another job, brutal but it's the way business works so why should it be different for them.
