Finding an objective book on economics, particularly focused on economic growth, can be challenging due to the inherent biases in various economic ideologies. A recommended approach is to explore multiple perspectives rather than seeking a single book. Notable suggestions include "New Ideas From Dead Economists" by Bucholz and "Classical Economics Reconsidered" by Sowell, which provide balanced views on different economic theories. Additionally, studying influential economists like Friedman, Hayek, Lucas, and Keynes can offer insights into the diverse schools of thought in macroeconomics. Arnold Kling, who identifies as a "libertarian Keynesian," also provides valuable commentary on current macroeconomic issues through his writings and blog. Overall, the discussion emphasizes the complexity and lack of consensus in economic thought, suggesting that complete objectivity may be elusive.
