The LibLabCon one-party state has been having fun recently in the General Election, with various members accusing each other of terrible evils. But just take a look at the different plots they have for 'repaying' British government debt. They're so close, that the red one representing the Labour party is hidden underneath the yellow one of the Liberal Democrats. (See here, for much more.)
'Just about identical' and 'indistinguishable by the human eye' are the phrases which spring to my mind, when looking at these debt curves.
Yes, there really is no discernible difference between any of them; whatever you do and whoever you vote for, the British government is going to get back in again.
Democracy is a God that has failed.
