Michael Sandel's What Money Can't Buy purports to demonstrate that markets corrupt - degrade - the goods they are used to allocate. Therefore we as a society should deliberate together about the proper meaning and purpose of various goods, relationships, and activities (such as baseball) and how they should be valued. I don't think Sandel's critique of markets quite holds together. Nor do I find his communitarian political solution attractive. But the book does succeed as a provocation: it evokes a healthy attitude of critical resistance to what may be called rapacious capitalism.
