For me the Common Market started so well, so full of hope and enthusiasm, and for years it was just fine and worked well for everyone
I think it never worked that well, nigglynellie - remember the over-production of food resulting in 'wine lakes', 'butter mountains' etc
Oversupply and its redistribution
To perpetuate the viability of European agriculture in its current state, the CAP-mandated demand for certain farm produce is set at a high level compared with demand in the free market (see § CAP as a form of state intervention). This leads to the European Union purchasing millions of tonnes of surplus output every year at the stated guaranteed market price, and storing this produce in large quantities (leading to what critics have called 'butter mountains' and 'milk lakes'), before selling the produce wholesale to developing nations. In 2007 in response to a parliamentary written question the UK government revealed that over the preceding year the EU Public Stock had amassed "13,476,812 tonnes of cereal, rice, sugar and milk products and 3,529,002 hectolitres of alcohol/wine", although the EU has claimed this level of oversupply is unlikely to be repeated. This point was actually proven in January 2009, where the EU had a store of 717,810 tonnes of cereals, 41,422 tonnes of sugar and a 2.3 million hectolitre 'wine lake', showing that the stocks had diminished dramatically.
The food crisis in 2008, which saw the stocks empty out and the prices skyrocket, even introduced a popular demand for the introduction of emergency stocks of agricultural produce in the EU, which would help stabilise prices both on the very volatile markets
Too much interference or a sensible approach to stabilising the markets? It could be argued either way, but it does mean a high level of interference in agricultural policy.
