Competitive advantage is a companys ability to perform in one or more ways that competitors cannot or will not match.

Thomas Edison had great visions (for lights, music players, movies, etc.) but he knew they didn't count until he could make them work. His statement that creativity is 99% perspiration makes that point. Consider how much time he spent trying to make a synthetic rubber material for tires and never stopped trying but he never succeeded.

I would favor three policies: raising the minimum wage to $12, closing the tax loophole where persons only pay a 15% income tax on long term capital gains (tax it at the full tax rate), and institute a progressive tax moving the highest tax rate from 39.6% to 45%. I would favor implementing these three policies in that order, starting with raising the minimum wage, but not stopping there.

The theory of marketing is solid but the practice of marketing leaves much to be desired.

Strategy is indeed about choosing what not to do as well as what to do. A business unit needs to decide what need it aims to satisfy in what group of people and with what value proposition that distinguishes the business from its competitors.

My primary early interest was in marketing and my aim was to improve its theories, methods and tools. Early on I pressed companies to adopt a consumer orientation and to be in the value creation business. I didn't pay much attention to the social responsibilities of business until later. Now I am pressing companies to address the triple bottom line: people, the planet, and profits. I found that companies were too much into short term profit maximization and they needed to invest more in sustainability thinking.
