Naw, the bankers in the UK are insanely too powerful and they have more or less adopted the position that "if anyone left of Bismarck ever comes to power and tries to CHANGE anything, we are going to PURPOSELY tank the fucking economy overnight."
And somehow, the British have not strung these people, these bankers who are elected by nobody, up by their intestines, even though they make these threats in the open.
When you read "so and so is afraid of the City" this is what they mean.
