Interesting article about this in the Times of London:

Of course what Vodafone doesn't say...they justify high roaming rates by saying they have to reimburse the operator one is roaming on...right...so if I'm in Germany with a Vodafone UK sim and roaming on Vodafone DE, Vodafone UK has to reimburse Vodafone DE and passes along the price to me.....but of course when Vodafone UK "reimburses" Vodafone DE all that is happening is the money is going from the left pocket to the right pocket, or it vice versa.
What a bunch of malarkey.
