Most people—and many philosophers—shudder at these questions. To put some goods and services for sale offends human dignity. If everything is , then nothing is sacred. The market corrodes our character. In this expanded second edition of , Jason Brennan and Peter M. Jaworski say it is now past time to give markets a fair hearing. The market does not, the authors claim, introduce wrongness where there was not any previously. Thus, the question of what rightfully may be bought and sold has a simple answer: if you may do it for free, you may do it for money. Contrary to the conservative consensus, Brennan and Jaworski claim there are no inherent limits to can be bought and sold, but only restrictions on we buy and sell.
