The Australian and international wine glut is an example of market forces working normally. The call for vines to be pulled, with either implied or express government subsidies, is human nature working normally: the desire to privatise profits and socialise losses.
There’s nothing new about wine industry figures calling for vine culling. In the early 1980s, the Federal and South Australian Governments were paying growers millions of dollars to do it. Then along came the Australian wine revolution and that subsidised destruction became the stuff of infamous legend.
