Pretty sure if all dairy farmers said we want X amount, as long as it reasonable, then they would have to pay it, where else will they get milk from if they don't.
The way I see it, unless I am totally wrong, is that dairy farmers pretty much own the milk supply business, as in without them there is no milk on the shelves, pretty sure if milk went up 20 cents no one would give a flying fuck, I am a tight arse and budget well, but really could not care less if milk costs 20 cents more if that is what it takes.
