"It all depends on the situation – that is the point. Sceptics like me always look at the concrete situation, question it, think about it – and then decide. Government measures to support demand are not per se evil. Insofar John Maynard Keynes was right at the time, and he prevailed in the scientific dispute against Hayek. I personally witnessed that – Hayek never got over this defeat and attributed it more to the general Zeitgeist than to scientific knowledge. After the war, he changed from being a strict economist to become a social philosopher. He developed a theory of cultural evolution of society, which is very deterministic and contradicted his previous scientific beliefs...[…] In my eyes, both of them are advocates of the market economy, but with a different emphasis. Keynes was a very sceptical mind, this is why I feel more closely related to him. […] His lesson is the following: it is not the case that the market is always good and the government is always bad, that the market is always rational and the government always acts irrationally. There are good and bad governments, just as there are good and bad functioning markets."
