This book argues for the abolition of the employment system in favor of workplace democracy and thus escapes the usual capitalism-versus-socialism binary choice by reframing the basic issue as the employment contract, not private property or a market economy. 
The author repositions the political and economic debate in the lineage of abolitionism - against the owning of other people - which in its modern version of neo-abolitionism would also abolish the renting, or hiring, employing, or leasing of other people.
The overall argument is based on three recovered theories, each one of which is sufficient to yield the neo-abolitionist conclusion. These three rights-based theories are developed throughout the book. The three theories are 1) inalienable rights theory, 2) the natural rights or labor theory of property, and 3) democratic theory as based on a democratic constitution that only delegates governance rights versus a non-democratic constitution that alienates governance rights. 
The book, therefore, is a must-read for everybody interested in a better understanding of the political economy, workplace democracy, rights-based theories, and the employment system.
