Most farmers are land rich, cash poor...Plus, they've potentially been passing wealth down, tax-free, for generations, have they not?
And they will be forced to sell up to large corporates who won't give a monkey's about what is best for the UK...
But as you mention 'passing wealth down, tax-free, for generations', what do you have to say about the royal family being exempt?
Or such hangers on like the Duke of Westminster?
They pay nothing or next to nothing when it comes to IHT!
