This book is well written and well documented. It is a philosophical approach to the socio-economic inequalities that exists in the world today. As the author implies, these conditions have always existed, and will possibly continue forever. For a similar book that is more focused on the inequalities of Americans and solutions to the causes, read: SHARING THE LAND OF PLENTY: NO ONE DESERVES TO EARN THAT MUCH MORE (2020) A shorter read with possible solutions based on Socialist models.
