Such a view has the veneer of realism, without the substance. If any- thing is more naive than an unquestioning belief in the transformative power of social entrepreneurs, it is an unquestioning belief in the trans- formative power of national governments, international organizations, and multinational corporations. As already indicated, in many parts of the world where change is most urgently needed, governments are as likely to be part of the problem as part of the solution. In such envi- ronments, all institutions structured to work through national govern- ments face serious handicaps. The 21st-century relevance of the United Nations and the World Bank—the two institutions most clearly tasked in the post-World War II order with addressing global challenges—is no more assured than that of social entrepreneurs.
