The Importance of Voluntary Action in Social Transformation

Wealth is not created through exploitative economic systems such as rent extraction from dependent conquered territories, or slavery. What that does actually is to enrich small minorities, but it doesn't lead to a general increase in social wealth and well-being. That's the great argument against things like slavery as a key economic institution. It works really nicely for a small class of slave owners, but it don't work well for creating wealth for societies and all.
