Although Keynesian Nobel laureate Paul Krugman praised Friedman as a "great economist and a great man" after Friedman's death in 2006, and acknowledged his many, widely accepted contributions to empirical economics, Krugman had been, and remains, a prominent critic of Friedman. Krugman has written that "he slipped all too easily into claiming both that markets always work and that only markets work. It's extremely hard to find cases in which Friedman acknowledged the possibility that markets could go wrong, or that government intervention could serve a useful purpose."

In her book The Shock Doctrine, author and social activist Naomi Klein criticized Friedman's economic liberalism, identifying it with the principles that guided the economic restructuring that followed the military coups in countries such as Chile and Argentina. Based on their assessments of the extent to which what she describes as neoliberal policies contributed to income disparities and inequality, both Klein and Noam Chomsky have suggested that the primary role of what they describe as neoliberalism was as an ideological cover for capital accumulation by multinational corporations.
