Their labour, their minds and their lives are consumed by someone else's greed. It is not about legal ownership, it is not about buying and selling people, and it is not about race or colour. Slavery today may include any of these things, but they are not essential to enslavement. Past and present Slavery exists in many different forms around the world. This new kind of slavery arrived in the late 20th century.
Slaves are cheaper than they have ever been.
The fall in their price has been so dramatic that the basic economy of slavery has changed. When the price of anything drops so much, supply and demand change as well. Today there is a glut of potential slaves on the market, and that means they are worth very little. This in turn means that a slave does not require special care as a major investment, and it means slaves are easily replaced. If slaves get ill, are injured, outlive their usefulness or become troublesome to the slaveholder, they are dumped or worse.
