I read this book at the same time as that of Marc Sundeen "The man who gave up money." This is a militant approach that is written and described by one who conduct. This book presents itself as both a record of strong experience, practical advice as a guide for those wishing to enter a money off approach. It is less pleasant to read than the first, but provides the clear advantage of presenting what "Freeconomy" and offer websites in French to take action. I recommend this book to all those who want to wean overconsumption.
