The Entrepreneurial State - Mariana Mazzucato
A profoundly important book. Your iPhone - and most other high tech stuff - is based off state-sponsored research. For every Venture Capitalist saying "the free market made this possible" there is an army of publicly funded developers. Sometimes, in the case of GPS, a literal army!
It makes a compelling case for the funding of basic and experimental research and development. We need long-term planning, rather than short-term profit chasing.
My only criticisms of this book are based on me not reading many academic books. I don't understand how a reference that just says "Smith (1904)" is helpful to anyone. It is also repetitive - I suspect because it is a collection of related essays, rather than a unified book. I also wonder whether it is normal for an author to continually cite their own work.
Either way, it clearly presents a well-researched argument and exhaustively demonstrates its veracity.
