This is a book about macroeconomic principles, but is not just a rehash of existing theories. It abounds in new ideas as well. In addition to conventional theories of classical, neoclassical, and Keynesian economists, it examines the impact of rising inequality on employment and economic growth. It also has a chapter on stock market bubbles and crashes. The book argues that demand-side tax cuts are superior to supply-side tax cuts. It shows that regressive taxation is a major cause of current economic ills. Finally, the book offers new reforms.
