"But in spite of the shortcomings of his analysis, Marx had raised some basic questions. I was deeply concerned from my early teen days about the gulf between superfluous wealth and abject poverty, and my reading of Marx made me ever more conscious of this gulf. Although modern American capitalism had greatly reduced the gap through social reforms, there was still need for a better distribution of wealth. Moreover, Marx had revealed the danger of the profit motive as the sole basis of an economic system: capitalism is always in danger of inspiring men to be more concerned about making a living than making a life. We are prone to judge success by the index of our salaries or the size of our automobiles, rather than by the quality of our service and relationship to humanity -- thus capitalism can lead to a practical materialism that is as pernicious as the materialism taught by communism."
