The Economics of Growing Dairies

Dairy Carrie has a good interview with a dairy farmer (surprise).  It briefly outlines the reasons dairies keep expanding and why they use immigrant labor.   I remember my uncle's operation, I think in the neighborhood of 50 cows, which he ran mostly alone, though sometimes he had hired hands and/or a housekeeper (he was a German-American bachelor farmer).  Not much time for other things, unless your barn burns and you have a heart attack, which gives you an exit strategy.
