We loved it too and are very much hoping that there will be another series! It certainly underlines how hard they all work for very small rewards and how inherently unfair and slanted is the current system which does not reward the real workers properly.
A friend's DH is unable to retire because the family don't get enough income from their cows to enable them to employ a dairyman in his place so, as she says, he will have to carry on working until he dies.
It is very hard, the supermarket gives them less per pint of milk than they did 20 years ago and so they have had to absorb all the rising costs just to keep their farm going. One does wonder just how long all this is sustainable to the farmers particularly when not every farm can diversify due to location, size and many other factors. The scenery may be beautiful but that does not pay the bills and you cannot eat it either!
