How excellent, we appear to have 90 MPs who do not know what they are talking about. Not unusual, of course:

A cross-party group of 90 MPs, including the Tory leader David Cameron,
is calling on the Office of Fair Trading to be given powers to ensure
that dairy farmers receive a fair price for their milk.

Exactly what is a ‘fair price’ and how is it to be determined? One that allows a farmer to make a profit? Why? Should the price of words written be regulated to ensure that writers can make a profit? Why? There are more poeple who would like to write words for pay than there are people willing to pay them to do so.

There appear to be more farmers willing to produce milk than there are people willing to pay them a profitable price for doing so. Why are farmers special and writers not?

Fair prices are those that willing buyers and sellers reach: if there really is a monopsony (or oligopsony) in the purchase of raw milk then fine, investigate that. But fixing prices to make them fair? When and where will it all end?
