Ok, this might be controversial, but….
Farms that have been in a family for generations, and the current owner plans to continue farming should not have inheritance tax levied on them. If a farm is sold, then additional tax can be paid at that point.
Million/billionaires buying farms for the purpose of avoiding inheritance tax (Clarkson) or obtaining millions of pounds in subsidies (Dyson) should be paying double.
The people producing food are already getting screwed over on prices, and the suicide rate among farmers is scarily high. We should be helping these people, not victimising them for protesting or crippling subsequent generations when they start.
But no, they shouldn’t be blocking public rights of way or trying to intimidate people. But that’s not just farmers, that’s money-hoarding land-hoarding bastards too like those on Dartmoor.
