This book is clearly a product of the 1990s - optimistically thinking that capitalism and American-led globalization will solve all our problems. Written just 8 years after the collapse of the Soviet Union, he was obviously influenced by Francis Fukuyama's "End of History".
The Great Recession had proven the techno-Utopian ideas in the book wrong, and Karl Marx is far from irrelevant to my generation the Millennials, to whom globalization offers a very bleak future.
Still, I think it's an important book to read to understand where neoliberals are coming from. Friedman is pretty compassionate for one of their kind.
