20% of the world's population owns 80% of its land and most of those people live in western europe. This has numerous effects because at times natural resources are destroyed to build factories (aka sweat shops) with abysmal working conditions that the native population have no choice but to work at. Also, many farmer in Africa are essentially sharecropping because native Africans often pay rent to some company owned by some British/Dutch/French/German noble to farm their own land. Do we think we've defeated exploited labor just because we don't see it anymore in Western countries?
