The world economy keeps crashing with many incidence of inflation. What is happening at the moment is a clear indication of a world that has failed the minority. Although the underdeveloped countries could partly be blamed for the high inflation that exists in their respective economies. Would things turn around for good if underdeveloped countries start to add value to their natural resources themselves without selling to the countries with good economy?
Many underdeveloped countries do not have the infrastructure to transform their natural resources into something else that they can sell, so they do not really have any option and they have to export those resources to other countries, you may not like it but that is the way it works.
The current economic system has failed everyone except those that are at the very top and take the decisions since they know what it is going to happen and when and they can take advantage of this.
