On the surface this explanation doesn&#x27;t make sense. Is there a correlation between extremists and countries with high income inequality? If so, provide some evidence apart from cherry picking countries which happen to have high inequality and other problems. Why aren&#x27;t free democratic regimes which also have high inequality equally plagued by these problems?<p>Also, energy prices have fallen dramatically, affecting the coffers of many middle east governments. I don&#x27;t know why he doesn&#x27;t address this.<p>Maybe he addresses these issues in his actual research but it is missing from every piece trying to link inequality to all societies ills.
