Yet in spite of all of the evidence to the contrary, the US today keeps preaching free-trade and low tariffs to developing countries such as those in Africa.
For over 50 years the US has dominated World financial organization, such as the International Monetary Fund, the World Bank and the World Trade Organization. They have enforced economic policies on developing countries that are exactly the opposite of what the people of those countries need.
The IMF and World Bank make loans to countries at times of their desperate need. These loans come with strict conditionality's. The bankers say the conditionality's are for the good of the recipient. More likely the bankers are more concerned about being repaid their loans with interest.
The IMF, World Bank and the World Trade Organization are a strong cabal backed by US military might. The Cabal's loan-making powers usurp the recipient's economic and political sovereignty, and recipients lose the control of their own destinies. The Cabal is the loan-shark to the world. The U.S. military might is the muscleman and enforcer.
