The response to Rajan's paper at the time was negative. For Example, former U.S. Treasury Secretary and former Harvard President Lawrence Summers called the warnings “misguided” and Rajan himself a "luddite". However, following the 2008 economic crisis, Rajan's views came to be seen as prescient; by January 2009, The Wall Street Journal proclaimed that now, "few are dismissing his ideas." In fact, Rajan was extensively interviewed on the global crisis for the Academy Award-winning documentary film Inside Job. Rajan wrote in May 2012 that the causes of the ongoing economic crisis in the US and Europe in the 2008–2012 period were substantially due to workforce competitiveness issues in the globalisation era, which politicians attempted to "paper-over" with easy credit. He proposed supply-side solutions of a long-term structural or national competitiveness nature: "The industrial countries should treat the crisis as a wake-up call and move to fix all that has been papered over in the last few decades... Rather than attempting to return to their artificially inflated GDP numbers from before the crisis, governments need to address the underlying flaws in their economies. In the United States, that means educating or retraining the workers who are falling behind, encouraging entrepreneurship and innovation, and harnessing the power of the financial sector to do good while preventing it from going off track. In southern Europe, by contrast, it means removing the regulations that protect firms and workers from competition and shrinking the government's presence in a number of areas, in the process eliminating unnecessary, unproductive jobs."
