Over the last 30 years, the US has been riding on an economic roller-coaster involving multiple bubbles, a financial crisis, and a struggling middle class. To escape this turmoil and another depression, the U.S. will have to view its economy through the profit frame and adopt better policies that promote sustainable profits and growth. Investors and policy-makers who understand the most important question in economics can avoid the turmoil and make better, more informed decisions about economic and financial risk. "Where do Profits Come From?" gathers the most important pieces of the global economic puzzle, properly assembles them, and examines the cascading series of events under the current global rules that promote instability, inadequate business investment, ultra-low interest rates, quantitative easing, rising income inequality, and ultimately future austerity. Fortunately, the road to economic prosperity offers a solution to the turmoil that is consistent with game theory. By enforcing balanced trade without punishing trade and better managing the sources of profits, policymakers can restore business investment and insure sustainable growth without the need for future bubbles or the risk of another depression.
