The hallmark of a global economy is greater mobility of economic transactions and economic agents. Firms and households enjoy far more geographic choice for purchases of goods and services, for locations to invest, and for places to work and retire. Policy choices have tilted the playing field toward the rich and corporations.Over the last four decades, income inequality has increased dramatically, income growth for the vast majority has slowed to a crawl, and progress in closing gender and racial wage gaps has been either too slow or nonexistent. This paper examines the evolution of the corporate profit base and the relationship between book income and tax income for U.S. Corporations over the last two decades. The paper demonstrates that this relationship has broken down over the 1990s, and it has broken down in a manner consistent with increased tax-sheltering activity.
