As to dairy? well it would be better for the economy if the little two bit dairy farms with old equipment and poor hygiene standards closed or merged eventually evolving into something with critical mass that can compete. Sometimes you can only flog a dead horse for so long and Tasmania is so resistant to change that the economy has been stagnant for decades.
