The power of economic thinking can be explained by seven core principles, which are accountability, investments, economy, incentive, freedom of choice, nondiscrimination, and one price.

By understanding and incorporating these principles, better decisions will be made on individual, corporate, and government levels.

To explain this thesis, the author offers analyses of key economists who have changed their views over time, an examination of major domestic and international issues, and an explanation of how economists can predict which politicians will be successful.
