...[M]odern-day Americans are still complicit in slavery. We buy a wide range of goods, from chocolate to cars, that include ingredients or components from the hands of forced or even slave labor... In September 2001, plantation owners, cacao traders and chocolate manufacturers agreed to the Harkin-Engel Protocol...and [to] develop a certification to reassure consumers that their chocolate was not made with forced child labor... Alas, the chocolate industry has yet to develop that certification... But the protocol is changing human rights conditions on the ground... Forced child labor and slavery will only stop when companies use their market power to prod their first-tier suppliers, who in turn will force their vendors not to rely on forced labor. But policymakers...have an important role to play here, too. [refers to Toyota, General Motors, Frigidaire (part of Electrolux)]
