If you are planning on visiting Venezuela any time soon, don't plan on being able to drink milk, or eat anything with butter, eat ice cream or cheese. Hugo Chavez is so put out with farmers looking to get fair market value for their dairy products that he is threatening to seize their cattle.
I predict that the price of Venezuelan beef is going to drop sharply in the near future. And all dairy products will be almost totally unavailable.
Because price supports always, always work. Except when farmers get greedy.
