The pawn shops, the half-finished and overgrown housing developments on the edges of towns, the roads to nowhere and the new proliferation of beggars and down-and-outs on the streets of New York (I have not seen so many here since the 1980s) are a growing testament to the President’s challenge. He has yet to prove he is equal to it.

Instead he has been trying, on a broad front, to fulfil the reformist ideal that informed his election campaign. Rather like a would-be government in Britain that talked of “sharing the proceeds of growth”, the candidate who wanted to redistribute wealth now, as President, has no wealth to redistribute. A $3.6 trillion budget showed little sign of addressing the problem of stimulating demand. Both big corporations and small businesses feel overtaxed, their competitiveness hampered, and incapable of creating jobs at a time when they are desperately needed. Mr Obama’s green agenda, which was also a significant part of his election promises, entailed higher taxation that will retard the economy just when it needs to grow. His greatest ambition – of starting a national health service – seems impossible in the present climate. As he seeks to move forward on this broad front Warren Buffett himself has attacked him, saying that his first three priorities should all be the economy. Paralysed by inexperience and a Blairish desire to be liked, and hampered by inadequate senior staff, he is now finding that even some of his own party in Congress feel he has gone too far in the socialist experiment.
