Successful countries and the European Community also buy mountains of staples, including grains, meat and butter, stockpile them, and sell some at a loss or donate some to keep their agricultural sector satisfied and maintain food security. Go to Hong Kong. A lot of the chicken sold is from France, and pork is from Denmark.
They view the loss as a necessary price to pay for social peace, food security, and a peaceful and productive agricultural sector that supports prices provide. The free-market USA that our Washington Consensus types think they are emulating does the same. So does Japan. Why? Food security for countries with substantial populations is not something to leave to the vagaries of the market. It is a necessity for a stable country.
