The Campaign For Real Ale (CAMRA) may be a fine example of the free market working well. One of the little known facts about the organisation is that the most important figure in it's early years was the editor of the Socialist Worker. It may not be going to far to say that CAMRA is a Trotskyite entryist organisation hell bent on the destruction of the free market. On the other hand it may be going to far.
In support of this consider the appearance of Viz's "Real Ale Twats" with a typical meeting of middle aged Trots.
