This book recommends balance between cooperation and competition in intercultural/international relations, with more emphasis on the former. To make this possible, it describes a paradigm shift and demonstrates why it is logical and how it can be attained--thus going beyond traditional legal and moral compliance. Compliance has been insufficient because morality has been significantly dismissed as a "soft value," and civil rights laws have been circumvented and frequently ineffective. Book proposes that revolutionary changes caused by globalization require an equivalent paradigm. Interdependence inherent to globalization will not function if winning-is-the-only-thing mindset continues to prevail in U.S. and the West. Cultural Complementarity is validated through respected principles and practices in quantum physics, education, business and economics. End chapters focus on national and international applications of paradigm. Appendices have data and suggested programs to test and implement the theory.
