“Jemandem das Blaue vom Himmel versprechen” – to promise someone the blue of the heavens – is to promise the unreachable. It is an attempt to persuade via promises which have “weder Hand noch Fuss” – neither hand nor foot.

To exaggerate, to paint a rosy picture of future developments is not in any way convincing to Germans. This might be one of the reasons why they are so sceptical about utopias of every kind.
