From Cinderella Released:
[Dr. Kevin Bales] described slavery as a human being that is being controlled by violence or threat, working without payment, and being economically exploited. A slave can’t walk away from his/her life without making the choice he would rather starve than be a slave. Slavery only exists because of human greed. He explained why the supply and demand of slaves and human trafficking had risen so dramatically over the past 50 years. He explained, “It is due to wars, conflicts, globalization, global warming, but particularly, kleptocracies.” These are governments that extends the personal wealth and political power of government officials and the ruling class (collectively, kleptocrats) at the expense of the population.
