Perception of dairy farming a long way from reality

If New Zealanders do not want dairy farming why don't they just say so? Some people have it in their heads the dairy industry is filled with over-stocked, chemical-laden, corporate-owned farms, being run by ill-treated migrant workers, where the effluent runs willy-nilly into streams and the milk is collected by a faceless corporation and adulterated in a factory until virtually undrinkable and sold to the public at extortionate prices.I am fairly closely associated with the New Zealand dairy industry and have been for a long time and in my experience, nothing like the above fictional farm exists or will exist.I have been on literally hundreds of farms for discussion groups over the years and by and large most of them are run by normal, conscientious, environmentally aware, hardworking families who are just milking cows so they can get by.
