The greatest division in mankind, is economical slavery from debt. The puppeteer behind the whip towards society would be the major banking industries. Produced and originated by people such as Rockefeller, etc. Money, is in fact enslavement. Money is created through debt, for it is loaned. Once distributed it creates more promises on repayment. No debt = No value within money. Once this debt is created, a society will be created as well. We form industries, jobs and more, therefore economical enslavement is created. Once these foundations are in place society lives through it. "There is two ways to conquer the world. One by sword, the other debt."
