Does the free market erode moral character?

Here is a link to a symposium with contributions from a number of economists, scientists, politicians and former world chess champion, Garry Kasparov.

This is Tyler Cowan's opening bit:

In matters of morality, the free market functions like an amplifier. By placing more wealth and resources at our disposal, it tends to boost and accentuate whatever character tendencies we already possess. The net result is usually favorable. Most people want a good life for themselves and for their families and friends, and such desires form a part of positive moral character. Markets make it possible for vast numbers of people, at every level of society, to strive for and achieve these common human ends.
