This is the point of the harmful part of a productive + harmful economic system: obtaining income not through productive means, but by unproductive means–taking it away from others.   The central idea of this website is that one group uses resources to restructure the alternatives of the second group in such a way that the first group benefits.  Slavery would be an example.  This is discussed in the following sections: Harm through the market, Obtaining income through the government – rent seeking – corruption, Discrimination: race – gender – ethnic – religious – class, Discrimination against women, Slavery, forced labor,  Crime, Control of land and natural resources.
