In America, we are not lacking solutions. We are lacking a two-party system that is willing to agree on solutions. Part of this is due to rigid ideological positioning that substitutes for really thinking about the facts and solutions.

CEOs need to produce continuous growth in sales and profits. Yet they must also invest in sustainability and social responsibility, which then leave them less money for financing their growth.

I found marketing to be highly descriptive and prescriptive, without much of a foundation in deep research. I brought in economics, organization theory, mathematics, and social psychology in my first edition of Marketing Management in 1967. Today Marketing Management is in its 15th edition and remains the world's leading textbook on marketing in MBA programs. Subsequently, I wrote two more textbooks, Principles of Marketing and Marketing: an Introduction.

There is much work to do to protect forests from over-timbering and oceans and lakes from over-fishing. We need to encourage and reward companies that create jobs to reduce the carbon footprints of offices and buildings and homes.

I admire firms that have achieved a real differentiation from their competitors. Nike is all about mastering sports. Apple is all about creating technologies to make life easier and better. Audi is is all about introducing new technologies to make automobiles safer and better performing.

I admire companies that have a purpose, passion, and performance. I am a fan of Unilever under its CEO Paul Polman, not only for the company's insights into women and men when they buy beauty products or skin products (the DOVE woman, the AXE man), but also as a company seeking to achieve both growth and practicing social responsibility.
