Dr. Paul Krugman writes a regular column for the New York Times, so those familiar with his column will find this book familiar - and his analysis and solutions easy to understand and brilliant.
Essentially, Krugman proves - through countless examples - how the demand side (government intervention) has rescued the supply side (banking and industry) over the last century. Yet the uniformed or idiotic right wing (can you separate them?) either deny the facts, don't know them or are 'ideologically' opposed to them. This book originally focused on the Latin American and Asian banking crises but has been expanded to deal with the onset of the great 2007-8 disaster we are still living with.
Krugman has consistently advocated massive public capital infusion (about 4% of GDP in the US) to lift the economy (the US actually put in less than half, a figure Krugman long predicted would be insufficient) and a new regulatory set up for the Non-bank banking sector (hedge funds, etc.) which never happened.
The Obama administration was too timid to enact a real Keynesian push (opposed by the right wing Republicans and scared Democrats) and the current Tory lead government is producing precisely the wrong program (refuted countless times in this slim volume) for recovery.
It was Gordon Brown, Alistair Darling and Ed Balls who were on the right path, but did not explain to the 'great British public' why the UK deficit had to balloon in the short term to stave off depression. Of course, the public punished Brown for saving the British economy, and swallowed whole the Conservative's version of events, believing that we should punish ordinary citizens for the excesses of the few (who are, of course, all richer as a result of the crisis). Ed Balls regularly refers to Krugman, and rightly so - he is a beacon of clarity in these dark days.
Read Krugman as a first step to seeing what macro-economists really know about what starts and how to contain, economic crises.
