Don't blame China for these global economic jitters

The truth is that there has never been a real recovery from the 2008 crisis in North America and western Europe. According to the IMF, at the end of 2015, inflation-adjusted income per head (in national currency) was lower than the pre-crisis peak in 11 out of 20 of those countries. In five (Austria, Iceland, Ireland, Switzerland and the UK), it was only just higher -- by between 0.05% (Austria) and 0.3% (Ireland). Only in four countries -- Germany, Canada, the US and Sweden -- was per-capita income materially higher than the pre-crisis peak.

These asset bubbles have been most dramatic in the US and UK. They were already at an unprecedented level in 2013 and 2014, but scaled new heights in 2015.

Whether or not the recent market turmoil leads to a protracted slide or a violent crash, it is proof that we have wasted the past seven years propping up a bankrupt economic model. Before things get any worse, we need to replace it with one in which the financial sector is made less complex and more patient, investment in the real economy is encouraged by fiscal and technological incentives, and measures are brought in to reduce inequality so that demand can be maintained without creating more debts.
