An article Walter Block and I wrote opposing school vouchers a long time ago was included in the For-Profit volume of the Opposing Viewpoints book series. I got a copy in the mail today, and it looks great. It’s also available via amazon (referral link).
Opposing Viewpoints is a long-running series that dedicates a whole volume to each of a range of controversial topics. The books present the major issues and sub-issues in a pro–con format using articles, cartoons, quotations, and other materials collected from many sources. They’re designed to give children a fairly balanced overview of the topics from all the major sides.
