The market could only reward ideas that turned a profit. Nobody stood to profit from clean parks; they were just nicer to live with than dirty parks. But if nobody made the political judgment that clean parks were better, a society organized around profit incentives from production alone would almost automatically end up with dirty parks. The market was not an impartial guide to the beliefs of the public, and some of its verdicts were crazy…. When public goods fell into disorder or neglect, people found them unpleasant and satiated their desires with what the market had to offer…. The economic organization of society was devoted not to maximizing social comfort and harmony but to satisfying the consumer desires created by advertising and production itself. And that in turn was hampering society’s ability to grapple with poverty. 

Kenneth Galbraith, according to Zachary D.Carter in The Price of Peace
